Array

a “container” that can hold many specific bits of information of the same type (like a bunch of last names or a bunch of phone numbers) A collection of data items with each identified by a subscript or key and arranged in such a way that a computer can examine the collection and retrieve data from these items associated with a particular subscript or key.

Console

the place you can type commands that are interpreted and some sort of output occurs immediately. The section of a computer that is used to control the machine manually

Syntax

the rules of typing or speaking a language

Java Script

Iterator

something that causes a repeating step by step process to examine data

var

JavaScript command to create a variable

Function

a small portion of a larger computer program that performs a)specific task (or tasks) and can be called upon to repeat the process by other parts of the program

Global

variables or data that is available to any part of a computer program

local

variables or data that is only available within a specific function or specific small part of the whole program

parameters

Values or information required by a function or procedure

arguments

the specific actual values given to function or procedure when it needs parameters in order to run.

Scope

he range in which a variable or function or other programming object can effect other parts of a program. Variable declared inside functions can only be used inside of those functions.

variable scope

Boolean

a type of data expressed after items are compared most often resulting in determining if a situation (or combination of conditions) are met. If the conditions are met, the situation is true, if not it is false

Branch

a part of a computer program that runs only when a specific condition is met.

Recursive

repeating a process or a part of a computer program many times until all processing is complete.

infinite

loop-a computer program that exhibits recursion, forever, or until the user forcefully stops or quits the program. This is almost always due to an error in programming.

return
