JS: Find largest number in array of objects

Question

What's the easiest way to find the largest number in an array of objects and return that object?

var arr = [ { num: 0.5 }, { num: 1 }, { num: 0.35 }]

Tried to use forEach but couldn't work out a way to do this, other than storing every number and comparing them.

Any help is appreciated. Thanks in advance.

reduce will do the job:

var maxObj = arr.reduce(function(max, obj) {
  return obj.num > max.num? obj : max;
});
