The sort method of array takes a custom comparator method as an optional parameter:

myArray.sort(function(a, b) {
  if(a[0] > b[0]) {
    return 1;
  } else {
    return -1;
  }
});

You can just subtract too:

myArray.sort( function( x, y ) { return x[0] - y[0]; } )

By using Jquery sort() function you can achieve this.

Here is the Fiddle for your question.

myArray=myArray.sort();

Edit

Rightly pointed out the default sort function wont work as we want to thus solution will be as George Houpis pointed out.

myArray.sort( function( x, y ) { return x[0] - y[0]; } )

-Help :)

Put this in array also `[10,"Titel"], [20,"Titel"]`. Will see that it doesn't work as expected. https://jsfiddle.net/q03q8a8a/1/ – charlietfl Jan 18 '16 at 05:07
