  1. What is an expression?

A fragment of code that produces a value, every value that is written is an expression. An expression between parentheses is also an expression, etc.

  1. What is a binding?

bindigns, such as (let) assign values. This does not mean that if you assign vales that they are going to be held forever, you can always change the value of an expression with an operator (=) again. Or you can change the volume of the value with other operators such as (+,-,*,/ etc.)

You can use (var,const) similar to (let)

  1. What is an environment?

The collection of bindings and their values that exist at a given time is called the environment. Bindings which provide ways to interact with the surrounding system also count.

  1. What is a function?

Functions are a type of value which is a piece of a program, wrapped in values. Executing a function is called invoking, calling or applying. Values given to functions are called arguments.

  1. Give an example of a function.

In a browser environment, the binding (prompt) holds a function that shows a little dialog box asking for user input.

  1. What is a side effect?

A lot of functions are useful because of te side effects they produce, such as in the example above with the little dialog box appearing. This dialog box is the side effect. Naturally this isn’t the only side effects functions can have.

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

a) prompt(“Enter passcode”)

b) console.log(Math.max(2, 4))

  1. What is control flow?

When a program has more than one statement, the statements are executed in a specific order: left to right, top to bottom. But there are exemptions.

  1. What is conditional execution?

If you want a program to do something else than what it would do originally if something specific happens, or a specific value comes out, etc. it is called a conditional execution. If that happens do that, if this happens do this, etc.

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

(if)

1 - expression is a series of variables, operators, and method calls that evaluates to a single value

2 - Binding is an association of method call to the method definition

3 - An Environment variable is a dynamic “object” on a computer that stores a value, which can be referenced by one or more software programs

4 - A function is a reusable portion of a program, sometimes called a procedure or subroutine

5 -
z=1
1
w=2
2
r=z+w

6 - A side effect is the modification of state through the invocation of a function or expression

7 - Function that produces a value.:
function increment(number) {
return number + 1;
}
Function that produces side effect…
alert(" Function that produces side effect")

8 - Control flow is the order in which instructions, statements and function calls being executed or evaluated when a program is running.

9 - The if / else statement executes a block of code if a specified condition is true. If the condition is false, another block of code can be executed.

10 - if or/and Else

  1. What is an expression?
    It is a fragment of code that produces a Value.

  2. What is a binding?
    It is a way to store values that can be used later. You use the “let” statement to define one or more bindings. You can define a specific value to a binding, so everytime you use that binding, the value you applied to it before, will display and be used by the code.

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

  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.
    Executing a function is called invoking, calling, or applying it. You can
    call a function by putting parentheses after an expression that produces a
    function value.

  5. Give an example of a function.
    alert (“hello world”)

  6. What is a side effect?
    Showing a dialog box or writing text to the screen is a side effect.

  7. Give an example of a function that produces a side effect and another function that produces a value.
    Produces a value=
    “the function Math.max takes any amount of number
    arguments and gives back the greatest.” —> console.log(Math.max(2, 4)); —> // → 4
    Produces a Side effect= prompt (“How’s it going?”)

  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.

  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.
    We may, for example, want to create
    a branching road, where the program takes the proper branch based on the
    situation at hand

  2. Bindings are variables that can be named and stored.
  3. An environment is a collection of variables and their values that exist at a given time in a program.
  4. A function is a piece of a program wrapped in a value.
  5. Console.log(“Good day to you!”); will print “good day to you!” in the log.
  6. A side effect is the output of the function, for example, a side effect could be a dialog box or writing text to a screen.
  7. If I enter an alert(“Hello world!”) within the console of google chrome then the side effect will be for the web page to say “Hello world!”. The function Math. min takes whatever number arguments it is given and gives back the smallest value. An example of Math. min would be console.log(Math. min(3, 4) + 150); which would result in the result 153.
  8. This is the direction of how the JavaScript emulator reads your code step by step, in this case, it is left to right and down, as we type.
  9. Conditional execution is simply thought of as “if X happens, then do Y, else do Z”
  10. The kind of keyword do you need to use to invoke conditional execution is “if”.

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

  2. What is a binding?
    You should imagine 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?
    e collection of bindings and their values that exist at a given time is called
    the environment

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

You can call a function by putting parentheses after an expression that produces a
function value. Usually you’ll directly use the name of the binding that holds
the function. The values between the parentheses are given to the program
inside the function.

  1. Give an example of a function.
    For example, in a browser environment,
    the binding prompt holds a function that shows a little dialog box asking for
    user input. It is used like this:

prompt(“Enter passcode”);

In the example, 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?

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

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

prompt(“Enter passcode”); Side effect.

console.log(Math.max(2, 4));
// → 4
When a function produces a value, it is said to return that value. Anything
that produces a value is an expression in JavaScript, which means function
calls can be used within larger expressions.

  1. What is control flow?

The statements are executed as if they are a story, from top to bottom.

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.

  2. Binding is giving statements values by indicating what you want the value to be by typing the statement = Value. My Age = 35 or 5 * 7. Now that a statement is binded it can now be use as an expression.
    console.log(My Age - My Age)
    0
  3. A collection of bindings that exist at any given time that provide ways to interact with the surrounding system.
  4. A function is a piece of programing wrapped in a value. Values can be applied in a default environment to have a type of function.
    5.Funtions produce side effects. Showing a dialog box or writing text is also a side effect.
  5. console.log(Math.min (3,6)) =3 console.log(Math.max (3,6) +100) = 106
