    champions.slice(0,3).map(function(ch         


        

Answer 1

Use Array.prototype.sort() with a custom compare function to do the descending sort first:

champions.sort(function(a, b) { return b.level - a.level }).slice(...

Even nicer with ES6:

champions.sort((a, b) => b.level - a.level).slice(...
