    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

  1. An expression is a fragment of code that produces a value. Expressions can contain other expressions that contain other expressions. Or a value written literally can be an expression.

  2. Bindings are used to catch and hold values, useful for tracking state in your program.

  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. It takes an input and returns an output.

  5. Example of function: console.log(5*5)

  6. A side effect is what happens if there is a change in the internal state of the machine in a way that will affect statements that come after it.

  7. Side effect function: prompt(“Enter password”);
    Value producing function: console.log(Math.max(2,4));

  8. Control flow is the order in which the computer executes statements in a script.

  9. Conditional executions perform different computations or actions depending on whether a programmer-defined boolean condition evaluates to true or false.

  7. prompt() produces a side effect, Math.max() produces a value
  8. Control flow describes the execution of statements within the program.
  9. Conditional execution uses a value in order to decide what to do next in the control flow.

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

  2. A binding is the same as a variable. This lets you define a piece of data that can be stored.

  3. The environment is a collection of all the bindings and the values that exist. Even in an empty program there are bindings from the language itself.

  4. A function is snippets of code that wrap a program. It can be as simple or complex as the developer writes it.

  5. let x = B(4, 3);
    function B(a, b) {
    return a * b;
    }

  6. A dialog box or written text can be examples of a side effect.

  7. Side Effect creates a dialog box for the answer: let a = ((4*2)>3)&&((6-3)>20);
    alert(a);
    Value: console.log(Math.max(2, 4));

  8. Is a program with more than one statement. The code is initiated top to bottom the same as a book.

  9. This is called upon if the developer wants to curve away from a straight line program. Loops can split the program but bring it back to the ending.

  10. These can be made by if, else, if and only if, while, and do.

    4./5. A function is a piece of a program in the default environment. Examples of functions are console.log, prompt.
  4. Side effects are often produced by functions and they can be very useful.
  5. For example, prompt function shows a dialog box. A function that produces value can be math.max.
  6. Control flow is when a program contains more than one statement and they are executed from top to bottom.
    9./10. Conditional execution is best shown with the keyword IF, when we want our program to do something if and only if something else is satisfied.

An expression is a fragment of code that represents a value
A binding is a variable that programs an expression to hold a specific value consistently
An environment is the collection of expressions and their functions which create a context for interaction with the language
A function is programming tied to specific values to create the default environment
An example of a default function would be the programming of the variable “prompt” to provide an input form in a web browser environment
A side effect is one of the possible results of a function
The input form field would be an example of a side effect of the “prompt” default web browser function, but another result of a function besides a side effect could be the simple return of a value
The control flow allows the code to read as a logical, sequential language by taking the top statement and continuing to build or alter it depending on the subsequent statements
Conditional execution is when a statement is given that asks for more than one possible function depending on circumstances
Conditional executions can be programmed by adding statements with keywords like “if” after statements with keywords like “let”

  4. A function is a wrapped section that performs a specific task
  5. console.log(""), is a function which outputs some information to the console.
  6. Side Effect is a function which produces an expression and returns value. Showing a dialog box or writing text to the screen. A change

  1. An expression is a piece of code that produces a value.
  2. A binding is the attachment of a variable to a value.
  3. An environment is the total of variables, bindings and the attached values at given time, which are contained in the computers memory.
  4. A function is a piece of program wrapped in a value.
  5. the prompt(“something”) function crates a dialog window that says “something”.
  6. A side effect is the output of a function that affects the screen, it is usually a dialog box or writing text.
    7.Here is an example of a function that produces a side effect: prompt(“ENTER NAME”);
    Here is an example of a function that produces a value: console.log(Math.max(2,4));
  7. Control flow is the order in which statements are executed in a script.
  8. Conditional execution is a branching of the control flow , usually initiated by the keyword “if” which results in the computer checking whether or not the conditions, that were set by the programmer, are met before executing the function that follows after the " if (condition) " statement.
  9. You use the the “if” keyword followed by the condition , which is stated inside parenthesis, if the condition is met the program proceeds to execute what is in the curly backets {} , if the condition is not met you can add the keywords " else if" after the brackets to make the program check for another condition, which again is followed by curly brackets {} , the content of these curly brackets is then executed if the conditions are met.

  1. What is an expression?
    A fragment of code that produces a value is called an expression.
  2. What is a binding?
    To catch and hold values, JavaScript provides a thing called a binding, or variable. The special word (keyword) let indicates that the sentence is going to define binding. It is followed by the name of the binding and if we want to immediately give it a value, by an = operator and expression.
  3. What is an environment?
    The collection of bindings and their values that exist at a given time is called 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 a program wrapped in a value.
  5. Give an example of a function.
    prompt (“Enter passcode”)
  6. What is a side effect?
    A statement stands on its own, so it amounts to something only if it affects the world. 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 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.
  8. What is conditional execution?
    Conditional execution is created with the if keyword in JavaScript.

FYI, some of the questions I could not find the answers.
