Script Preparation code:

function getRandomUint32(min, max) {
    return Math.floor(Math.random() * (max - min) + min);
}

Tests:

Compare to half of max int
for(let i = 0; i < 100; i++) { const z = getRandomUint32(0, 2 ** 32) < 2_147_483_648; }
Mod even/odd
for(let i = 0; i < 100; i++) { const z = getRandomUint32(0, 2 ** 32) % 2 === 0; }
Bitwise even/odd
for(let i = 0; i < 100; i++) { const z = getRandomUint32(0, 2 ** 32) & 1 === 1; }
