}

var arr = [];
for(var i = 0; i < 100000; i++){

Tests:

_.sortBy
_.orderBy(arr,"value");
array.prototype.sort
arr.sort((a,b) => a.value - b.value);
other
var sort = function(array) { var len = array.length; if(len < 2) { return array; } var pivot = Math.ceil(len/2); return merge(sort(array.slice(0,pivot)), sort(array.slice(pivot))); }; var merge = function(left, right) { var result = []; while((left.length > 0) && (right.length > 0)) { if(left[0].value > right[0].value) { result.push(left.shift()); } else { result.push(right.shift()); } } result = result.concat(left, right); return result; }; sort(arr);
Stable Sort
const stableSort = (arr, compare) => arr .map((item, index) => ({item, index})) .sort((a, b) => compare(a.item, b.item) || a.index - b.index) .map(({item}) => item) stableSort(arr, (a,b) => a.value - b.value)
