Sorting object in JavaScript array numerically

Question

var people = [{name: "lily", pts: 30}, {name: "harry", pts: 20}, {name: "jennie", pts: 10}];
points.sort(function(a, b){return b.pts - a.pts});

I want to sort everyone in array people by the number of points they have HIGHEST TO LOWEST (descending). is this correct?

Seems that the code is working. You just want to confirm that is it the correct way to do it. If that's the case then I say it is. — Maheer Ali

This is not an array of numeric arrays, he wants to sort an array of objects by a numeric field — virgiliogm

Your array is people. But you are sorting points. Just change it to: people.sort(....). Other than that, your code should work fine — adiga

Yes it's correct way to sort arrays in JavaScript. You can find more information here.

P.S. you should call sort function on your people array

people.sort(function(a, b){ return a.pts - b.pts; })

If you want to sort the "People" array, you just need to sort that array, independent of the attr name.

var people = [{name: "lily", pts: 22}, {name: "harry", pts: 20},{name: "jennie", pts: 18}];

The array.prototype.sort function wants to be called in the array.

people.sort(function(a,b){
return a.pts - b.pts })

it would be b.pts-apts as it's higest to lowest
