Sort by two values prioritizing on one of them

Question

How would I sort this data by count and year values in ascending order prioritizing on the count value?

//sort this var data = [     { count: '12', year: '1956' },     { count: '1', year: '1971' },     { count: '33', year: '1989' },     { count: '33', year: '1988' } ]; //to get this var data = [     { count: '1', year: '1971' },     { count: '12', year: '1956' },     { count: '33', year: '1988' },     { count: '33', year: '1989' }, ]; 

Answer 1

(See the jsfiddle)

var data = [     { count: '12', year: '1956' },     { count: '1', year: '1971' },     { count: '33', year: '1989' },     { count: '33', year: '1988' } ];  console.log(data.sort(function (x, y) {     var n = x.count - y.count;     if (n !== 0) {         return n;     }      return x.year - y.year; }));
