function randomInt
Usage in Deno
import { randomInt } from "node:crypto";
randomInt(max: number): number
Return a random integer n
such that min <= n < max
. This
implementation avoids modulo bias.
The range (max - min
) must be less than 2**48. 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('node:crypto'); randomInt(3, (err, n) => { if (err) throw err; console.log(`Random number chosen from (0, 1, 2): ${n}`); });
// Synchronous const { randomInt, } = await import('node:crypto'); const n = randomInt(3); console.log(`Random number chosen from (0, 1, 2): ${n}`);
// With `min` argument const { randomInt, } = await import('node:crypto'); const n = randomInt(1, 7); console.log(`The dice rolled: ${n}`);
