How to generate N unique random numbers between min and max in TypeScript

Answer 1

function generateUniqueRandomNumbers(N: number, min: number, max: number) {
    if (max - min + 1 < N) {
        console.log("Range is too small to generate the required number of unique numbers.");
        return;
    }

    const uniqueNumbers: Set<number> = new Set();

    while (uniqueNumbers.size < N) {
        const randomNum = Math.floor(Math.random() * (max - min + 1)) + min;
        uniqueNumbers.add(randomNum);
    }

    return Array.from(uniqueNumbers);
}

const N: number = 8;
const uniqueRandomNumbers = generateUniqueRandomNumbers(N, 1, 20);

console.log(uniqueRandomNumbers);
