  1. What is an expression?

An expression is a fragment of code that may consist of one or more operators, operands that evaluated to yield a value.

  1. What is a binding?

A binding is a reference or association of an identifier or variable to hold values .

  1. What is an environment?

An environment is the space that provide ways to facilitate interaction within the surrounding systems. In programming, the environment provides a set of process, values, variables and the programming tools to develop program or software product.

  1. What is a function?

A function is a block of organized codes that can be reused to perform a specific related task. It creates the output result from its input without having to know how it works internally. A function can be called from inside of another function.

  1. Give an example of a function.

Example is the math function sqrt () or the console.log function in the web browser that display the output in the console.

  1. What is a side effect?

Side effect means a function called can change the state of a variable or program outside of its scope.

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

Side Effect of a function that cause the global age being modified.
var age = 8;
function getAge(age) {
age = 6*age;
return age;
}

Pure function returns a new age without affecting the global variable age.
var age = 8;
function getAge(age) {
let futureAge = 6 * age;
return futureAge;
}

  1. What is control flow?

Control flow is to control and direct the order of the program flow instead of executing code statements sequentially by default.

  1. What is conditional execution?

Conditional execution is the part of the code is to be executed next based on the state of a evaluation or result of an action that satisfied the specified condition otherwise the program execution will branch to alternate flow path based on the evaluation of condition status.

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

The if, if…else if…, switch, for and while keywords can be use to invoke conditional execution.

  1. What is an expression?
    Expression is any piece of code that returns a value, expressions can be layered with other expressions making larger expressions.
  2. What is a binding?
    Binding is a value or string set to a variable. It helps to make bindings so you don’t have to write out the same expression multiple times in the program.
  3. What is an environment?
    Environment is the collection of bindings that exist at a given time.
  4. What is a function?
    Function is a piece of programming wrapped in a value. It is a line of code in the block that we can call as many times we need
  5. Give an example of a function.
    alert (“This is my script”), prompt…
  6. What is a side effect?
    Showing an alert or dialog box
  7. Give an example of a function that produces a side effect and another function that produces a value.
    Function that produces side effect is console.log
    Function that produces value is math.max
  8. What is control flow?
    Control flow is order in which statements are executed within a program.
  9. What is conditional execution?
    It apears and executes only if a condition is met.
  10. What kind of keyword do you need to use to invoke conditional execution?
    If/else

    var number1 = 35*2
  8. Control flow is the order that a program executes code

  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

  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. Such values can be applied in order to run the wrapped program. For example, in a browser environment, the binding prompt holds a function that shows a little dialog box asking for user input.

  5. Give an example of a function.
    Se above.

  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.
    The helper function in the farm example, printZeroPaddedWithLabel, is called for its side effect: it prints a line.
    console.log(Math.max(2, 4));
    // → 4

  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?
    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.

  10. What kind of keyword do you need to use to invoke conditional execution?
    Conditional execution is created with the if keyword in JavaScript.

  1. An expression is a fundamental part of the structure of a program, and basically it’s a fragment of code that produces a value.

  2. Binding is the process of obtain a value and hold it for using it in anytime in the future. It is a useful part of a program because once the value is kept through a binding name, it could be used as part of an expression.

  3. The environment is defined as the group of binding and expressions used to run a program in order to interact with the system.

  4. A function is the action wrapped inside a value.

  5. An example of a function is the operation of console.log (). It retrieves a messages and post it in the page, or it allows an specific operation to be performed inside the parenthesis .

  6. A side effect is any returned value obtained after using a function.

  7. Function that produces a side effect→ alert (“Hello”)
    Function that produces a value→ console.log (“hello”)

  8. Control flow is the order the codes are following in a program from top to bottom.

  9. Conditional executions are functions able to alter the regular flow of an script in a program, in such manner the flow might takes different ways.

  1. What is an expression?
    An expression is just a a piece of code that gives an outcome.

  2. What is a binding?
    A binding is an item that has been bound to a particular value or expression. It is more commonly known as a variable.

  3. What is an environment?
    It is the entire collection of bindings and their values at the current point in time.

  4. What is a function?
    A function is a piece of code that is wrapped in a value. It gives the program a set of instructions to apply the function.

  5. Give an example of a function.
    console.log();

  6. What is a side effect?
    A side effect is any change that occurs other than the return of the function output. Functions that produce other effects than simply giving an output are classed as having a side effect.

  7. Give an example of a function that produces a side effect and another function that produces a value.
    prompt is an example of a function that produces a side effect. Console.log is a function that produces a value.

  8. What is control flow?
    Control flow is just the order in which the script is read. The code is read from left to right, top to bottom, like you would read a book.

  9. What is conditional execution?
    Conditional execution is where a program can have multiple paths and takes the one it is told to based on the circumstances. The program is set up with multiple pathways that it could take, based on the information it receives.

    The keyword usually is the ‘if’ statement.

    In order to invoke a conditional execution in JavaScript, we use the keyword “if” and/or “else”.
