EcmaScript hasn't have the stable sort method yet. http://www.ecma-international.org/ecma-262/6.0/#sec-array.prototype.sort
Sure, we can create stable sort function by using `Array#sort`, by returning the number of index (e.g. `arr.indexOf(arguments[0]) - arr.indexOf(arguments[1])`) when it is equal to both arguments value in `comparefn`. But this is inefficient and perplexing. So, I propose below. `Array#stableSort(comparefn)` or `Array#sort(comparefn, isStable = false)` Thanks! _______________________________________________ es-discuss mailing list es-discuss@mozilla.org https://mail.mozilla.org/listinfo/es-discuss
