Benchmark created on

Setup

const objectsA = new Array(10000).fill({a:1});
const objectsB = new Array(10000).fill({a:1});

Spread
const spread = [...objectsA, ...objectsB];
const max = Math.max(...spread.map(object => object.a + 1));

Looping (Greedy Algorithm)
let max = -Infinity;
for (let array of [objectsA, objectsB]) {
	for (let object of array) {
		max = Math.max(max, object.a + 1);
	}
