JavaScript Array | All in One.

Array in JavaScript | Beginner Guide.

Summary
JavaScript array is an ordered collection of values. It is really helpful when you have values of the same kind. With arrays, you put all the values into one collection and refer them with a single name. Elements within an array are referred to in terms of the index. An index is nothing but a sequence of numbers starting from 0 then 1, 2, 3, and so on. Yes, it is starting from 0.
So the first element in the array is known as element/value at zeroth index.

There are 3 different ways to create a javascript array.
1. Array Literal/ Initializer ( Common )
2. Array Constructor

The number of elements in an array is retrieved with the 'length' property.
Multidimensional array for example 2 dimensional is used when two numbers are necessary to refer to a single element in the collection. for example matrix ( row number and column number are necessary to refer to a single element).
