#1567
  1. What is an expression? Every value that is written is an expression, ex 58 or physics.
  2. What is a binding? binding is to hold a value in javascript. we need bindings or variables.
    we use keyword like let folowed by the = operator and an expression.
  3. What is an environment? environment is a collection of bindings that exist at a given time.
  4. What is a function? A function is a piece of program wrapped in a value.
  5. Give an example of a function. prompt(“What is your name”);
  6. What is a side effect? Side affect is asking for users input.
  7. Give an example of a function that produces a side effect and another function that produces a value. let thenumber = Number(prompt(“pick a number”));
    console.log(“your number is the square root of” + thenumber * thenumber);
  8. What is control flow? programs that contain more than one statement. The statement is executed as they are a story.
  9. What is conditional execution? this is when the program doesn’t have a straight path and we want to create a branch road based on the situation at hand.
  10. What kind of keyword do you need to use to invoke conditional execution? Some key words are if, else, else if.

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

What is a binding?
Bindign gives and holds a value. However, it is possible to give new values with binding.

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

What is a function?
A function is a piece of program wrapped in a value

Give an example of a function.
prompt(“Enter username”);

What is a side effect?
A result of a function that is not the main purpose of it

Give an example of a function that produces a side effect and another function that produces a value.
alert(“oh no”);
console.log(Math.max(2, 4));

What is control flow?
The execution of the statements as if they are a story, from top to bottom.

  1. What is an expression? A fragment of code that produces a value. Any value that is written literally is an expression. What is written in parentheses is an expression. What is applied to both binary and unary operators are expressions.

  2. What is a binding? It allows a “new” value to be captured and stored. It requires a keyword to do so. And then the name of the binding. You must give it value for it to be stored.

  3. What is an environment? The collection of binding names and their values.

  4. What is a function? Is a piece of program from the default environment used to wrapped in a value.

  5. Give an example of a function. Square would produce the square of a value when called.

  6. What is a side effect? Something that is printed on the screen, or, a state that affects the statements that comes after it other than its return value.

  7. Give an example of a function that produces a side effect and another function that produces a value. Side effect. Prompt. Return value: Square or power.

  8. What is control flow? Statements are executed from top to bottom. And return values from higher statements are used in subsequent statements.

  9. What is conditional execution? The path the program takes is conditional on a condition being met. The program branches or forks off at that point.

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

  1. A fragment of code.

  2. Is a type of statement, such as var, a variable.

  3. The bindings and there values exist in an environment.

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

  5. alert(“Hello”);

  6. A visible change of the statement. A dialogue box, or writing some text in the screen.

  7. prompt?(“Enter Passcode”) is a function that produces a side effect.

And a value is, var a = 1

  1. When a program contains more than one statement. The statements are run as if they are a story.

  2. You create a branch road when the program looks like it is not following the path set, and you create a road where the program takes the proper road - conditional execution.

  3. if

  • What is an expression?
    A fragment of code which produces a value. Can be between parenthesis as a binary operator between two expressions, or unary applied to one.

  • What is a binding?
    A way that the program catches and holds values together. It does this by using the word “let”. After a binding has been defined (e.g. let ten=10), it’s name can be used as an expression.

  • What is an environment?
    An environment is a collection of bindings and their values that exist at any given time. Even when a program starts up fresh, there is an environment which consists of the language standard.

  • What is a function?
    A function is a piece of a program wrapped in a value.

  • Give an example of a function.
    For example, the word “prompt” is a function which creates a text box for the user to type in.

  • What is a side effect?
    Showing a dialogue box or writing text to a screen is a side effect.

  • Give an example of a function that produces a side effect and another function that produces a value.
    The function “console.log” produces the side effect of printing the text to the screen. The function Math.min is an example of a function which produces a value without a side effect.

  • What is control flow?
    Control flow is the order in which statements are carried out, depending on how the questions are answered. It is the flow of the story written into the code.

  • What is conditional execution?
    Conditional execution only occurs when some condition has been fulfilled (for example if a number is entered instead of a word).

  • What kind of keyword do you need to use to invoke conditional execution?
    You need to use the keyword “if” or “else” to invoke conditional execution.

  1. it is a fragment of code that produces a value.

  2. it is a function that can catch and hold a value. when a binding points at a value, that does not mean it is tied to that value forever.

  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.

  5. in a browser environment, the binding “prompt” holds a function that shows a little dialog box asking for user input. prompt(“Enter passcode”);

  6. A side effect is an application state change that is observable outside the called function besides returning a value. 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.

  7. console.log(firstAccount);
    var firstAccount = accounts[0];

  8. It is the direction of execution of code in JavaScript which happens in a top down approach.

  9. conditional execution is used when a website has input from a user, it allows the program to behave differently based on different information being entered or manipulated by the user.

  10. if, else, else if

1.What is an expression?

A fragment of code that produces a value is called an expression. Every value that is written literally (such as 22 or “psychoanalysis”) is an expression. Expressions can contain other expressions in a way similar to how subsentences in human languages are nested- a subsentence can contain its own subsentences, and so on.

2.What is a binding?

To catch and hold values, JavaScript uses binding, or variable.
It is a way how your program remembers things and stores them for later use.

3.What is an environment?

The collection of bindings and their values that exist at a given time is called the environment. Environment always contains bindings that are part of the language standard.

5.Give an example of a function.

function countApples (myApples,yourApples){return myApples+yourApples};

countApples(100,50);

150

This is an example of function that counts apples :slight_smile: or simple addition function that adds 2 values provide to it and returns a sum of arguments given to it.

6.What is a side effect?

When a statement in program makes a change in world, for example a dialog box popping up on screen- that counts as changing the world- or it could change the internal state of the machine in a way that will affect the statements that come after it. These changes are called side effects.

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

For example, the binding prompt holds a function that shows a little dialog box asking for user input. This is function that causes side effect.

For example, the function Math.max takes any amount of number arguments and gives back the greatest.

8.What is control flow?

When your program contains more than one statement, the statements are executed as if they are a story, from top to bottom. In some cases, it is straight line control flow and sometimes it can be conditional execution when sequence of execution has several branches. Control flow is basically when and what statement is executed.

9.What is conditional execution?

Conditional execution will make program execute statement only if certain condition is met.

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

Conditional execution is created with if keyword.

  1. What is an expression?
    -Any piece of code that produces a value.
  2. What is a binding?

  3. What is an environment?
    -The collection of bindings and their values that exist at a given time.
  4. What is a function?

  1. An Expression is a fragment of code that produces a value.
  2. A binding is a thing that catches and holds a value. they are comparable to tentacles rather than boxes. They don’t contain values, they grasp them.
  3. An environment is the collection of bindings and their values that exist at any given time.
  4. A function is a piece of program wrapped in a value. These values can then be applied in order to run the wrapped program. As an example, the binding “prompt” holds a function that executes a dialogue box for data input.
  5. function multiplyTwoByTwo() = { return 2*2;}
  6. A side effect is any change that is caused by our code. some way in which we slightly “changed the world”. for example, a function may have an effect that is not visible right now, but comes in handy later.
  7. an example for a side effect would be something like a prompt for a name. an example for a value can be seen above (answer 5)
  8. the order in which the program executes its decisions. It could be linear, or it could be an if/else situation that will take a fork in the road basically…
  9. it is the situation where the program goes one way IF a given condition is there, and go another way if another condition is there.

  1. An expression can be described as any part of code that produces a value. An expression can be literal as is in the case of the number 9 or a string such as “run”. An expression can even be contained within another expression by using parenthesis, as in the case where two expressions both contained within parenthesis have a binary operator between them. The fore mentioned line of code would be an expression in and of itself.

  2. A binding is a line of text that is used to link or “bind” that text to a value defined by the user. A binding can “let go” of a value and attach itself to a subsequent value defined by the user by re-invoking the binding name and attaching the new value on a line of the code that comes after the statement where the original value was “bound”.

  3. An environment is the entire set of bindings and values within a program. Usually there are preset bindings within most programs in order to assist in basic or commonly used functions such as tracking the location of the of the mouse pointer on the computer screen.

  4. A function is a program which needs to receive a value in order to run itself and return a new expression.

  5. Prompt

  6. A side effect is any meaningful change in the world that is caused by running a program. An example could be the accepting of a password in an entry field resulting in the side effect of a new web page being brought up on a screen containing personal or private information.

  7. A function that produces a side effect is Boolean. A function that produces a value is Math.max.

  8. Control flow can be described as a diagram displaying the order in which a program will run as well as what statements within the program will be executed depending what values are entered into each function within the program. A control flow chart should contain all possible paths of execution within a program.

  9. Conditional execution is when a function has more than one distinct subsequent statement of code that can be executed depending on what value is entered by a user. Conditional execution always has the capability or returning more than one distinct value in the console. In order for this to work the entered value has to meet a condition that is defined by an expression.

  10. if
