1This question is trivial and can be solved by reading the most basic introductory article on JavaScript arrays. It is unlikely to help future users.gyre– gyre2017-03-11 08:50:40 +00:00Commented Mar 11, 2017 at 8:50

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

if you want you output java this is sol :
var arr = [ 'java', 6 ];
alert(arr[0]);

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)
