  7. prompt(“enter password”) and Math.max(12,6) = 12
  8. Control flow is when your program consists of more than one statement
  9. Conditional statements consist of if else statements and only executes more of code if certain condition is fulfilled.

  1. Expression: A fragment of code that produces a single value (string, number, or logical value).

  2. Binding: Attaching a value to a chosen identifier within an environment. That identifier can be used to summon the value it’s tethered too.

  3. Environment: A collection of Bindings and their values that exist at any given time.

  4. Function: A piece of program wrapped in a value. A set of statements that performs a task or calculates a value.

  5. Number(prompt(“Pick a number”));

  6. Side effect: Any change that is observable outside the called function other than its return value such as displaying a dialog box or writing text to the screen.

  7. Example of with and without side effect:
    alert(“alerting the user with a dialog box is an example of a side effect”);
    let a = 1, let b = 2; console.log(a+b); produces the value 3

  8. Control flow is the order in which computers execute statements in a script. eg/in a straight line or branching .

  9. Conditional execution is a branching control flow where a particular branch is taken based on the situation at hand.

  10. Conditional execution is created using the “If” keyword.

  1. Any piece of code that produces a value.

  2. It’s a method used in JS to hold onto values inside the internal state (for later use).

  3. The environment is a set of bindings and their values that exist at a specific point in time.

  4. A function is a piece of program wrapped in a value. Parentheses are usually the wrappers of values, thus making them into functions.

  5. alert("Hello World");

  6. A side effect is a change in the internal state of a machine that is caused by an expression and has an impact on subsequent statements.

  7. prompt("Enter name") causes a side effect
    console.log(12/2) causes a value to appear.

  8. When you have more than one statement in your programme, the statements are executed in order, from top to bottom. This is the control flow.

  9. Conditional execution is when there is a sort of fork within the control flow, which can lead to a different outcome if the first condition is not met.

  10. Keywords needed are:
    if, else

  2. A binding, also known as variable is a way to catch and hold values.
  3. An environment is the collection of bindings and their values that exist at a given time.
  4. A function is a piece of program wrapped in a value.
  5. An example of a function is: prompt (“enter passcode”);
  6. A side effect is the showing of a dialog box or writing text to the screen.
  7. An example of a function that produces a value is the console.log (Math.min(2,4)); Its output is 4. A lot of functions are useful because they have the ability to produce side effects.
  8. Control flow is when your program contains more than one statement and the statements are executed as if they’re a story, from top to bottom (one after the other).
  9. Conditional execution is when programs aren’t straight and there’s a branching road created, which is where a program takes the proper branch based on the situation at hand.
  10. The kind of keyword that’s needed to invoke a conditional execution is “if” or “else”

1- A fragment of code that produces a value and every value that is written.
2- A thing to catch and hold values.
3- The collection of bindings and their values that exist at a given time.
4- A function is a piece of program wrapped in a value.
5- In a browser environment, the binding prompt holds a function that shows a little dialog box asking for user input.
6-The result of a statement that affect the world, the state of the machine or the next statement.
7- side affect= ( prompt(“Enter passcode”); )
value= ( (console.log(Math.max(2,4); )
8- Control flow is how your computer runs code from top to bottom. It starts from the first line and ends at the last line, unless it hits any statement that changes the control flow of the program such as loops, conditionals, or functions.
9- Not all programs are straight lines. Conditional execution is created with the keyword “if” and it decides on which way it will go according to the chosen conditions.
10- Conditional execution is created with the if keyword in JavaScript. You can also use the else keyword, together with if, to create two separate, alternative execution paths.

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

  1. What is a binding?
    Binding means recording or reference a variable in a specific Environment Record . Each Environment Record is related to a specific Execution Context /variable - and that binds the variable or function name to the this keyword for that execution context.

  2. What is an environment?
    The collection of bindings and their values that exist at a given time.

  3. What is a function?
    An amount of values provided in the default environment, i.e. a piece of program wrapped in a value. Such values can be applied in order to run the wrapped program.

  4. Give an example of a function.

  • Prompt(“Enter passcode”) ;
    We use parentheses after expression that produces a function value, directly using the name of the binding that holds the function. The value between the parentheses are given to the program inside the function. As above, the prompt function uses the string that
    we give it as the text to show in the dialog box. Values given to functions are
    called arguments.

  1. What is a side effect?
    Any application state change that is observable outside the called function other than its return value.

  2. Give an example of a function that produces a side effect and another function that produces a value.
    alert(“alert is a function that produces a side effect”)
    console.log(2+4); produces a value

  3. What is control flow?
    It is how computers runs code from top to bottom. It starts from the first line and ends at the last line, unless it hits any statement that changes the control flow of the program such as loops, conditionals, or functions.

  4. What is conditional execution?
    Conditional execution is created with the if keyword in JavaScript. In the simple case, we want code to be executed if, and only, if a certain condition is true. This is where conditional statements comes in and controls a program behaviour and determine whether or not pieces of code can run.

  5. What kind of keyword do you need to use to invoke conditional execution?
    There are multiple different types of conditionals in JavaScript including:

  • “If” statements: where if a condition is true it is used to specify execution for a block of code.
  • “Else” statements: where if the same condition is false it specifies the execution for a block of code.
  • “Else if” statements: this specifies a new test if the first condition is false.

  1. a fragment of code that produces a value
  2. It catches and hold values, they do not contain values; they grasp values.
  3. the collection of bindings and values that that exist in the program
  4. a function is a piece of program wrapped in a value
  5. console.log() or prompt() or login
  6. it could display something on the screen-that counts as changing the world-or it could change the internal state of the machine in a way that will affect he statements that come after it…(showing a dialog box or writing text to the screen is a same effect.)
  7. control flow is the way program is executed. JavaScript control flow is top to bottom like reading normally.
  8. the order in which the code is executed.
  9. where a program takes the proper branch based on the situation at hand. It’s created with “IF” keyword in JavaScript.
  10. we use the keywords “IF” and “ELSE”

1: An expression is a fragment of code that produces a value, in a language based interface it is considered part of a programming sentence.

2: A binding allows Javascript to catch & hold values, it’s basically how it remembers specific information & allows reference to them in the future.

3: An environment is the collection of bindings and their subsequent values that exist at a given time. An environment will also contain language standard bindings & necessary bindings to allow certain interactions within the surrounding system.

4: A function is a piece of program which is attached to a value.

5:
prompt(“Enter your name to continue”);

6: A side effect is a change within the Javascript world which has an effect visually or internally that effects all statements which come after it.

7:
let name = “Peter”;

8: Control flow is the executed path that the program takes (Generally from top to bottom, however this can vary dependent on the program).

9: Condition execution allows for the program takes different branches of the program’s path based upon the situation at hand.

10: Keyword statements such as ‘IF’, ‘ELSE’ or ‘ELSE IF’.

  6. side effects are produced by functions like writing a text to the screen
  7. prompt(“Text”) produces a side effect, Math.max produces a value
  8. It is a one way function depending on the values executed, when a program contains more than one statement they are executed from top to bottom, so the output is produced from one straight direction could be from a Boolean value for example
  9. Conditional execution is when a code is executed if, and only if, a certain condition holds
  10. You need the if function to invoke conditional exection

  1. ) An expression is a piece of code that produces a value

2.) Binding is using a keyword such as " let " to attach it to a value

3.) A environment is the present group of binding and values it is attached to at the given time

4.) A function is a piece of program wrapped in value such as “alert, and prompt”

5.) Prompt (“whats your favorite movie”);

6.) A side effect is a function that alters the state of the world it shows a display on the screen or can change the internal state of the machine in a way that will affect statements that come after it

7.) alert (“I am here”); would be a side effect since it alters the state of the world by having a alert pop up and console.log(20+9) produces a value

8.)The order which code is executed top to bottom

9.)When a program uses the situation at hand to respond to what its given, possibly given it another outcome

  1. An expression is a fragment of a code that produces a value. An expression between parentheses is also an expression as is a binary operator applied to two expressions or a unary operator applied as to one.

  2. Binding is created by a previous statement and it is called caught and uses it to grab hold of the number produced by number functions. The special (keyword) ‘let’ indicates that a sentence is going to define a binding.

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

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

  5. In a browser environment, the binding prompt holds a function that shows a little dialog box asking for the user input.It is used like this: prompt (“Enter passcode”);

  6. A side effect is showing a dialog box or writing text to the screen.

  7. The function Math.max takes any number of arguments and gives back the greatest.

  8. Control Flow are programs containing more than one statement, the statements are executed as if they are a story from top to bottom.

  9. Conditional Execution are non straight road programs. It occurs when the programs take a proper branch based on the situation at hand.
