Function randomInt

Return a random integer n such that min <= n < max. This implementation avoids modulo bias.

The range (max - min) must be less than 248. min and max must be safe integers.

If the callback function is not provided, the random integer is generated synchronously.

// Asynchronous
const {
  randomInt
} = await import('crypto');

randomInt(3, (err, n) => {
  if (err) throw err;
  console.log(`Random number chosen from (0, 1, 2): ${n}`);
});

// Synchronous
const {
  randomInt
} = await import('crypto');

const n = randomInt(3);
console.log(`Random number chosen from (0, 1, 2): ${n}`);

// With `min` argument
const {
  randomInt
} = await import('crypto');

const n = randomInt(1, 7);
console.log(`The dice rolled: ${n}`);
