  1. What is an expression?
    A fragment or piece of code that generates a value is an expression.

  2. What is a binding?
    A binding allows for javascript to catch and hold values for later use as it is currently defined. The binding can also be redefined to another value at any time. I.E variables.

  3. What is an environment?
    It is the collection of bindings and their values within a program.

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

  5. Give an example of a function.
    Prompt(Enter name) is a program that displays a dialog box whenever it is keyed in. Prompt is the function while the expression inside the parentheses will display on the dialog box.

  6. What is a side effect?
    A side effect is something like a dialog box or written text on the screen. These are produced by functions.

  7. Give an example of a function that produces a side effect and another function that produces a value.
    Prompt(insert) produces a dialog box vs. console.log(math.max) produces a value.

  8. What is control flow?
    It is the reading of statements from top to bottom in a program.

  2. They do not contain values; they grasp them—two bindings can refer to the same value.
  3. The collection of bindings and their values that exist at a given time is called
    the environment
  4. In a browser, there are functions to interact with the
    currently loaded website and to read mouse and keyboard input.
  5. It’s applying a coded action i.e. asking the user to interact (promtp (“Enter Passcode”);
  6. the box appearing and asking for an action is a “side effect”
    • prompt(“Enter passcode”); has the side effect of a prompting dialogue box. Console.log(Math.max(2, 4)); produces no side effect, though produces a value.
  8. the order in which we code, same as humans reading a book.
    1. Conditional execution means that some part of the code is going to be executed only if certain condition

What is an expression?

Its a code snippet/ a statement that evaluates to a value. It performs an actions and return a value to us. Anything that produces a value is an expression in JavaScript.

What is a binding?

Binding is another name of variables. It catches and values for us. We can use it whenever we need it to use. It has scopes so, if any binding is scoped inside a function you cant use it outside of that function. Global bindings can be used anywhere in the program.

What is an environment?

Environment is a data structure that provides storage space to the program execution enters their scope. It maps variable names to values that’s how variables comes into existence.

What is a function?

A function is a piece of program that contains a set of statements that performs a task or calculates a
value.

Give an example of a function.

function myFunction (number){
return number * number;
}
-----> This function performs multiplication and return the result when its being called with an argument.

What is a side effect?

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

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

alert(“Hello World”);

console.log(Math.max(2,4) + 20);
// --> 24

What is control flow?

Control flow is the order in which individual statements, instructions, function calls are evaluated or
executed.

What is conditional execution?

Specifically, conditionals perform different computations or actions depending on whether a programmer-defined Boolean condition evaluates to true or false.

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

  1. if…else
  2. While and do loops
  3. For loops

  1. An expression is a fragment of code that produces a value.

  2. Bindings keeps an internal state and remember things.
    They produce new values from old values. The old value
    is not changed though. And the new one must be used immediately
    or else it will dissipate.

  3. The environment is the data structure that provides storage space.

  4. Program that is wrapped in a value is function. Functions
    are applied to run the wrapped program.

  5. function ShowMessage ()
    }
    ShowMessage ();

  6. Side effects result in a change. They set or modify
    the value of a variable through the assignment operator.

  7. Side effect: function plusWithSideEffects (x,y)
    {
    alert (“This is a side effect”);
    return x + y;
    Value: function; function square(number) {
    return number * number
    }

  8. Control flow controls statements from top to bottom.
    That is, when a program contains more than one statement.

  9. Conditional execution is a branching road. The program
    takes the proper branch based on the situation at hand.

  10. if is the keyword used in Javascript for Conditional
    Execution, “if Block”.

1. What is an expression?
An expression is any value written.

2. What is a binding?
A binding is creating a reference or a hold on to a value from some expression.

3. What is an environment?
The collection of values and bindings that are present in the program.

4. What is a function?
A function is a piece of program that is wrapped in a value; functions cause changes in the system and get complete actions.

5. Give an example of a function.

let black = 25, white = 20;
console.log(Math.max (black, white));
//-> 25

6. What is a side effect?
Side effects produce an external change visible to the user (like dialogue box or prompt).

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

alert(“Enter if you dare.”);

Producing Value

console.log( Math.min(100,99.9));

8. What is control flow?
The process by which a program is executed, from top to bottom.

9. What is conditional execution?
A program that can take different paths depending on the inputs it receives.

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

  1. It’s simply a part of a code that creates a ‘value’. For example, 1+1 = 2. The expression here would be ‘1+1’ and the value is ‘2’. An expression within parentheses is also an expression e.g. (2+3). Moreover, an expression can be content that produces a value.

  2. A binding (i.e. variable) is a named value. It simply stores data(value) and gives it a name so that we can use it later on.

  3. It’s where your named values i.e. bindings are kept at a given time.

  4. It’s a part of a program which is named and executes certain tasks.

  5. prompt(“Enter passcode”)

  6. A side effect is when a function depends on, or makes changes to something outside its variables to do something. For example, a function which reads or writes from a variable outside its own values , data, or console can be said to have side effects. Showing a dialog box or writing text to the screen is a side effect.

  7. prompt(“Enter passcode”) is clearly a side effect as it shows a dialog box.
    console.log(Math.max(2, 4)) creates a value.

  8. It’s just the way we structure and order our coding language, as well as evaluate our statements.

  9. when we want to execute some of a code only if a specific condition is met. E.g. we want to find the square of the input data only if it is actually a number.

  10. One example would be ‘if’.

  8. The ability to have a program move in the expected direction based on the code.
  9. It is a condition in which the program will search for the branch in the road where the condition holds true and will execute upon that.
