javascript - Sorting array of numbers -


i have things pushed array (down below) , sort item(s) item price. tried using sort doesn't work me. after loop array , retrieve item name , item price.

pushing item array: array.push(itemname,itemprice)

trying use sort function: 

array.sort(function(a,b){     return b[1] - a[1] });

edit: agree nina's comment. changing compare function

looks need array of objects , define own comparison function sorting.

so need add element array this:

array.push({itemname:name,itemprice:price})

define custom comparison function

function compare(a,b) {   return a.itemprice-b.itemprice; }

use custom function

array.sort(compare)
