Benchmark: Reverse & find vs findLast

Script Preparation code:

const a = Array.from(Array(10000).keys()).concat(Array.from(Array(10000).keys()))

function shuffle(array) {
    let currentIndex = array.length,
        randomIndex;

    // While there remain elements to shuffle.
    while (currentIndex > 0) {

        // Pick a remaining element.
        randomIndex = Math.floor(Math.random() * currentIndex);
        currentIndex--;

        // And swap it with the current element.
        [array[currentIndex], array[randomIndex]] = [
            array[randomIndex], array[currentIndex]
        ];
    }

    return array;
}
const arr = shuffle(a)

Tests:

reverse & find
arr.reverse().find(x=>x===500)
