Binding, Functions and Control Flow - Reading Assignment

[Gregorius]

1. An expression is a fragment of code that produces a value.
2. Binding is a way to catch and hold values, that can be later used as an expression.
3. An environment is a collection of bindings and their values that exist at a given time.
4. A function is a piece of code wrapped in a value that can be executed by calling its name with proper arguments in parenthesis.
5. Math.min(5,8);
6. A side effect is any effect of calling a function other than producing a value, for example showing a dialog box.
7. Function Math.max(5, 9) produces a value and prompt(“Hello world!”) produces a side effect.
8. Control flow is an order of executing (or not) statements in a program.
9. Conditional executions allows to run portions of code only if specified conditions are met.
10. “If” and optional “else if” and “else”.

[Marv]

1. Singular values, or values derived out of combinations of several values via operators are expressions
2. Javascript uses binding to catch or hold values
3. The set of all variables and their values is called environment
4. A small program packed into a value. Typing the specific value like “alert”, executes the program, for example pops up a window with the alert function
5. answered with 4
6. A side effect can be a useful attribute of a function, for example the poping up of a window of the alert function
7. side effect-> alert function, value provider-> Math.max function
8. The direction in which a program is executed
9. In conditional execution only one of several options gets executed, depending on which condition gets fulfilled first
10. if, else, elseif

[Raf.PV7]

1. What is an expression?
   • A fragment of code that produces a value is called an expression.

2. What is a binding?
   • You should think of bindings as tentacles rather than boxes. They do not contain values; they grasp them – two bindings can refer to the same value.

3. What is an environment?
   • The collection of bindings ad their values that exist at a given time is called the environment. A program contains pre-determined bindings that are part of the language standard.

4. What is a function?
   • A function is a piece of program wrapped in a value. Such values can be applied in order to run the program.

5. Give an example of a function.
   • In a browser environment, the biding prompt hols a function that shows a little dialog box asking for user input;
   prompt(“Enter passcode”);

6. What is a side effect?
   • Showing a dialog box or writing text to the screen is a side effect. A lot of functions are useful because of the side effects they produce. Functions may also produce values.

7. Give an example of a function that produces a side effect and another function that produces a value.
   • Prompt(“hello world”);
   Console.log(Math.max(2, 4));

8. What is control flow?
   • It is the way the statements are executed as if they are a story, from top to bottom.

9. What is conditional execution?
   • Not all programs are straight roads. We may, for example, want to create
   a branching road, where the program takes the proper branch based on the situation at hand. This is called conditional execution.

10. What kind of keyword do you need to use to invoke conditional execution?
    • If

[RCV]

1. A fragment of code that produces a value is called an expression.
2. Binding is the way JavaScript holds onto an internal state and away for it to remember and store values.
   3.The collection of bindings and their values that exist at a given time is called the environment.
   4.A function is a piece of program wrapped in a value. Such values can be applied in order to run the wrapped program.
3. In a browser environment, the binding prompt holds a function that shows a little dialogue box that asks for user input.
4. A statement that changes the internal state of the machine in a way that will effect the statements coming after it.
   7.console.log produces a side effect, Math.max produces a value.
   8.When your program contains more than one statement, the statements are executed as if they are a story, from top to bottom.
   9.Not all programs are straight roads. We may, for example, want to create
   a branching road, where the program takes the proper branch based on the
   situation at hand.
   10.If

[BAAL]

1. What is an expression?
   A fragment of code that produces a value.
2. What is a binding?
   A variable that is defined in the code to catch and hold value(s). These include keywords such as break, case, catch, class, const, etc.
3. What is an environment?
   The collection of bindings and their values that exist at a given time.
4. What is a function?
   A piece of program that is wrapped in a value, to be applied in order to run the program.
5. Give an example of a function.
   prompt(“Enter passcode”);
   prompt is the bound function that shows a little dialog box asking for user input.
6. What is a side effect?
   A change to the internal state of the machine in a way that will affect the statements that come after it, so long as they affect the function.
7. Give an example of a function that produces a side effect and another function that produces a value.
   printZeroPaddedWithLabel \this prints a line as a side effect.
   zeroPad \this produces a return value which is more useful.
8. What is control flow?
   This is how the program is sequenced or executed, which is like a story from top to bottom.
9. What is conditional execution?
   A ‘branch’ in the code that executes a certain path if and only if certain conditions hold true.
10. What kind of keyword do you need to use to invoke conditional execution?
    A conditional keyword such as if & if else combined for more than 2 paths. Also while, do and for loops.

[HeigoH]

1. What is an expression?

2. What is a binding?
   Binding catches and holds values
3. What is an environment?
   The collection of bindings and their values that exist at a given time
4. What is a function?

   console.log(Math.max(2, 4)); Produces a value
   prompt(“Enter passcode”); Side effect
8. What is control flow?
   it means the statements are executed as if they are a story, from top to bottom
9. What is conditional execution?
   if we want to create a branching road, where the program takes the proper branch based on the
   situation at hand - thats called conditional exection - something is done in condition of smth.
10. What kind of keyword do you need to use to invoke conditional execution?
    if

[gobo]

• What is an expression?

  • A fragment of code that produces a value is called an expression
  • Every value that is written literally is an expression
  • An expression between parenthesis is also an expression

• What is a binding?

  • by using bindings a program can keep its internal state
  • by using bindings it can ‘remember things’
  • bindings catch and hold values

• What is an environment?

  • the collection of bindings and their values that exist at a given time
  • language standard bindings are often loaded into the environment by default

• What is a function?

  • … a piece of program wrapped in a value, which in turn can be applied in
    order to run the wrapped program
  • values used given to a program are called arguments

• Give an example of a function.

  • “square of a number function”:

    const square = function(x) {
      return x * x
    };
    

• What is a side effect?

  • Values returned after code execution in a dialogue box or as text written to
    the screen

• Give an example of a function that produces a side effect and another function
  that produces a value.

  • makeNoise, square

  • execution of code only if a certain condition is given

• What kind of keyword do you need to use to invoke conditional execution?

  • the if keyword

[Faz]

1. What is an expression?
   A fragment of code that produces a value.
2. What is a binding?
   Its a key word you can set for a value, it can be changed later but in short it is useful for remembering anything.
3. What is an environment?
   Collection of Bindings and their values at a given time.
4. What is a function?
   A lot of the values provided in the default environment have the type function. A function is a piece of program wrapped in a value.
5. Give an example of a function.
   function countapples(Janesapples,Bobsapples)
   {return Janesapples + Bobsapples}
   countapples (17+3);

so the above is all the function

Janesapples and Bobsapples are both bindings

6. What is a side effect?
   As the name suggests a side affect is the side effect/result of the function such as a display box
7. Give an example of a function that produces a side effect and another function that produces a value.
   The function I gave earlier in point 5 gives a value 20
   alert(“Hello”); has the side affect of the display box
8. What is control flow?
   The way the program is sequenced or executed from top to bottom like a story.
9. What is conditional execution?
   Conditional execution is created with the if keyword in JavaScript. In the
   simple case, we want some code to be executed if, and only if, a certain condition
   holds.
10. What kind of keyword do you need to use to invoke conditional execution?
    if

[motor929]

1. A piece of code that produces a value.
2. a binding is a variable or constant that allows you to catch and hold values.
3. The collection of bindings and their values that exist at any given time, including those that are part of the language standard…
4. A piece of program wrapped in a value.
5. prompt(“Username”);
6. Showing a dialogue box or writing text to the screen.
7. alert(“Hi”); produces a side effect, and Math.min(2, 6); produces a value.
8. It’s the flow or order of execution of a given program.
9. Conditional execution uses the if keyword, and only executes if specified conditions are met.
10. if

[ironmaiden1541]

   1.What is an expression?

code that produces value is called an expression. Every value
that is written literally is an expression. An expression can be content to just produce
a value.

2.What is a binding?

a variable that catches or holds a value.
let x = 4*6; these (keywords) var/const/let indicates that this sentence is going to define a binding.

3.What is an environment?

The collection of variables (bindings) and their values that exist at a given time is called the environment.
You can work on the environment via the browser,console or a text editor.

4.What is a function?

A piece of program wrapped in a value. Can be applied in order to run the wrapped program.
they hold keyword function followed by it’s name. After we assigned paranthesis that can hold
arguments, which hold values given to the function, followed by curly braces and the logic insided the
curly braces (body of the function).

5.Give an example of a function.

prompt(‘Enter name’); this binding prompt holds a function that shows a little dialog box asking for
user input …name.
console.log();

6.What is a side effect?

statements that display something or it could change the internal state of the machine in a way that
will affect the statements that come after it. Showing a dialog box or writing to the screen.

Give an example of a function that produces a side effect and another function that produces a value.
Math.max(3,6) => it produces a value. which is used to return that value.
prompt() => is a side effect function.

7.What is control flow?

A program that contains more than one statement being executed as if they are a story,
from top to bottom.

8.What is conditional execution?

a piece of code created with the if keyword to be executed followed by a certain condition
it it holds. A logical program that takes the proper branch based on the situation at hand.

9.What kind of keyword do you need to use to invoke conditional execution?
if/else if/ else

[theRealLos]

1. A fragment of code that produces a value.
2. It’s away to hold onto a value by pointing a variable to it.
3. It’s the existing universe of values and bindings at any given moment.
4. Functions a re program pieces that can be called upon by applying the value.
5. alert(“Danger!”);
6. A side effect is when a statement produces a change somewhere outside of its scope, such a dialog box in the browser.

prompt("This is a prompt");

console.log((4+2)>5);

8. It is the order in which statements are read and evaluated in a program.
9. It is when we determine that a statement be evaluated depending on a boolean value.
10. We can use if and else.

10. What kind of keyword do you need to use to invoke conditional execution?

1. An expression is any kind of content used to produce a value.
2. Binding is the process of storing a value in computer memory which can be re-used at a later time and can be referred to with a name.
3. All the bindings that exist when a program is started is called the environment.
4. A function is a block of code that returns a value.
5. alert (“This is a message”)
6. A side effect is the result of a function producing some state or effect outside of the current scope without returning a value.
7. Side effect: alert (“This is a message”) creates a prompt on the screen showing “This is a message”.
   Value: let val = 5*5 produces a value of 25 and sets the binding Val as 25.
8. The order in which statements are executed.
9. A certain block of code will only execute when a condition is met.
10. If and else

[LiewJunXian]

1.An expression is any fragment of code that result in a value or assign to a value.
2. A binding is a location or variable that hold a specific value, they grasps information and don’t hold them. It act like sort of a tentacle.
3.The environment is a collection of bindings and their value assigned that exist in a given time.
4.A function is a specifically created internal logic in a program section that is used to perform a specific task.
5.alert(“hi,world”);
6.A change in the program’s state caused by an expression or a function call in procedural.
7.prompt(“type your name”); (a dialog box or writing text to the screen is a side effect)
8.a control flow statements contains statements of different situation that can be execute with the right condition.
9. Conditional execution is created with the IF key word to fulfill a certain condition.
10.if and else

[carmen1408]

1. A fragment of code that produces a value is called an expression.

2. To catch and hold values, JavaScript provides a thing called binding or variable.

3. The collection of bindings and their values that exist at a given time is called the environment.

4. A function is a piece of program wrapped in a value.

5. Console.log

6. An operation, function or expression is said to have a side effect if it modifies some state variable value(s) outside its local environment.

7. Function as value:
   var BobsAge = 30;
   console.log(BobsAge);

   or

   function myFunction (a,b) {
   return a*b;
   }
   var x = myFunction (4,3);
   x

   Function with side effect:
   alert (“Hello, JavaScript”);

8. In a program, the statements are executed as if they are a story, from top to bottom. This is how we define control flow.

9. Conditional execution controls whether or not the core will execute an instruction.

10. The keyword for conditional execution is “if”.

[Daniel_Jude]

1. Expression: A fragment of code that produces a value.
2. Binding, or Variable: to catch and hold values. After a binding has been defined, its name can be used as an expression. The value of such an expression is the value the binding currently holds.
3. Environment: The collection of bindings and their values that exist at a given time.
4. *function: A function is a piece of program wrapped in a valued.
5. function c() {
   console.log(“Hello World”);
   }
   c();
   var d = “Live in Peace”
   console.log(d)
6. Side affect: changes the intenal state of the “machine” in a way that will affect the statements that come after it.
7. let amount = 1;
   while (amount <= 10){
   amount = amount + 2;
   }
   console.log(“after the count is done”, amount);
8. Control flow: This is the way Javascript executes code. Its not always top to bottom but in the order of operations.
9. Conditional Execution: “If this happens then let this happen” These are loops with keywords such as if, else, while, true, or false.
10. Conditional Execution Keywords: 1. if, else, else if , while.

[TrevorBicking]

1. What is an expression?

A fragment code that produces a value is called an expression.

2. What is a binding?

In JavaScript you use “Bindings” to catch and hold values for future use.

3. What is an environment?

Is a collection of bindings and their values that exist at a given time.

4. What is a function?

A piece of program wrapped in a value.

5. Give an example of a function.

prompt(“Enter passcode”);

6. What is a side effect?

The result that a function produces. An example of a side effect is showing a dialog box or writing text to the screen as a result of a function.

7. Give an example of a function that produces a side effect and another function that produces a value.

Function: prompt(“Enter passcode”); gives you the side effect of a Dialog Box asking for the passcode.

Function: console.log produces a value

8. What is control flow?

When your program contains more than one statement, the statements are executed as if they were a story from top to bottom (control flow)

9. What is conditional execution? Not all programs are straight roads. An example of a conditional execution is when a programmer wants to create a branching road, where the program takes the proper branch based on the situation at hand.

10. What kind of keyword do you need to use to invoke conditional execution? “If” keyword in the case of JavaScript

[Annegret]

1. A fragment of code that produces a value is called an expression. I explain by metapher. The operator is the verb, the value the subject and object, the expression is the complete sentence, finished by an semicolon.
   2.To catch and hold values, JavaScript provides a thing called a
   binding, or variable. We define and group values, and we are binding the definition name and the value by operators. The name can be used after definition as an expression.
   3.The collection of bindings and their values that exist at a given time is called
   the environment., it contains bindings. When a programme is starting, the envirement is never empty.
   4.A function is a piece of program wrapped in a value. The values in a function are called arguments.
2. console.log is a function. It creates an text output in the device.
   6.Showing a dialog box or writing text to the screen is a side effect
   7.Math.max produces value and console.log a side effect.
3. The control flow is the way of execution of the statements. When your program contains more than one statement, the statements are executed as if they are a story, from top to bottom
   9.By using the word “if” we create special conditions in the way of executing. It depends on the situation how the stateemnts will be executed.
4. The keyword are “if” and “else”.
