Script Preparation code:

function getRandomArray() {
    const arr = [];
    for (let i = 0; i < 10000; i++) {
        Math.floor(Math.random() * 100000) + 1;
    }
    return arr;
}

var randomArr = getRandomArray()

Tests:

Modulo
const x = randomArr.map(x => x % 2 === 1)
bitwise AND
const y = randomArr.map(x => x & 1 === 1)
