Generate a weighted random number in given range

const weightedRandom = (min, max) => ~~(Math.pow(Math.random(), 2) * (max - min)) + min;

const weightedRandom = (min: number, max: number): number => ~~(Math.pow(Math.random(), 2) * (max - min)) + min;

weightedRandom(2, 10);  // 7
weightedRandom(2, 10);  // 6
weightedRandom(2, 10);  // 4
weightedRandom(2, 10);  // 3
weightedRandom(2, 10);  // 5
