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}`);
