Javascript arrays are have their indexes start at 0. So, arr = [ 'java', 6 ] contains 2 elements. And since arrays have their index start at 0, 'java' would be at the [0] index and '6' would be at the [1] index. To access it you just need to do arr[0] and output it with, for example, console.log(arr[0]) which is the simplest way to access 'java'. (e.g You can do arr[i] where i is a number with a value of 0)

alert(arr[0]);

Use indexing; 0 for 'java', and 1 for 6. To get 'java', just do arr[0]
