What is an array ?

Answer 1

Its like a Variable that stores multiples values

For example

The variable

var name = "Alok";

Stores the value "Alok"

But if you are (for example) a teacher and want to type every name into a variable, you would have to create a lot of variables

But if you use an Array, you just need to declare one variable

For example

(With variables)

var name1 = "Alok";
var name2 = "Kenan";
var name3 = "Robert";
var name4 = "Tim";
...

(With an Array)

var names = ["Alok", "Kenan", "Robert", "Tim" ... ];

You just declared one variable, with multiple values

Also u need to use these brackets [ ] and seperate each value with an comma ,

Answer 2

A list of items you can access by index value. 0 to n-1. The course covers them well if you take your time reading through it.
