Sorting a list of lists in javascript

I'm trying to sort a list of lists in ascending order based on the second element in javascript. I'm following this answer javascript sort list of lists by sublist second entry but my list remains the same.

var a = [ [[1,2,3],10], [[5,6,7],0] ]
a.sort(function(x,y){return x[1] > y[1];});

var a = [ [[1,2,3],10], [[5,6,7],0] ]
a.sort(function(x,y){return x[1] - y[1];});

Use - instead of >.

Instead of comparing them with >, you should subtract one from the other using - to sort in ascending order:

var a = [ [[1,2,3],10], [[5,6,7],0] ]
a.sort(function(x,y){return x[1] - y[1];});
