Script Preparation code:
const toSearch = []; for (let index = 0; index < 5000; index++) { toSearch.push({ x: Math.random(), y: Math.random() }); } toSearch.push({ x: 1, y: 1 });
Tests:
Loop
let max = 0; for (let i = 0; i < toSearch.length; i++) { if (toSearch[i].x > max) { max = toSearch[i].x; } }
Math.max.apply
let max = Math.max.apply(null, toSearch.map(function (o) { return o.x; }));
Reduce
let max = toSearch.reduce((acc, value) => { return (acc = acc > value.x ? acc : value.x); }, 0);
Sort
toSearch.sort((one, two) => two.x - one.x); let max = toSearch[0].x;
