Access Array Data with Indexes

We can access the data inside arrays using indexes.

Array indexes are written in the same bracket notation that strings use, except that instead of specifying a character, they are specifying an entry in the array. Like strings, arrays use zero-based indexing, so the first element in an array is element 0.


var array = [1,2,3];
array[0]; // equals 1
var data = array[1]; // equals 2


Create a variable called myData and set it to equal the first value of myArray using bracket notation.
