Setup

const numbers = [];
const booleans = [];
const strings = [];
const objs = [];
const objsMega = [];
const coercion = [];
const coercionMega = [];
const mix = [];
const mixSelector = [numbers, booleans, strings, objs]

for(let i=0; i<1000; i++) {
	numbers.push(i);
	booleans.push(i%2 == 0);
	strings.push('' + i);
	coercion.push({valueOf: () => "" + i});
	objs.push({});
	objsMega.push({
		['_' + i]: i
	});
	coercionMega.push({
		['_' + i]: i,
		valueOf: () => "" + i
	});
	const array = mixSelector[i%mixSelector.length];
	mix.push(array[i]);
