What is array?

In JavaScript, the array is a single variable that is used to store different elements. It is often used when we want to store a list of elements and access them by a single variable. 

we write array values in square brackets [ ]

Example: 1

                     0         1        2       <————– index(its counts form 0 to n)          

var cars =[“bmw”, “audi”, “lexus”];

document.write(cars);

OUTPUT:- bmw,audi,lexus

We can print particular element value of array with the help of index number.

Example: 2

 0         1        2       <———— index(its counts form 0 to n)      

var cars =[“bmw”, “audi”, “lexus”];

document.write(cars[1]);

}
