Random number out of three number in js

Question

Hi I wanna get random numbers out of 2,3,5 . So i use this code.

function Random(low, hi) {
     return Math.floor(Math.random() * (hi - low + 1) + low);
 }

But this is only for 2 numbers , But i wanna get for 1 time for example 3 for 2 time 5, and 3 time 3 , but of course not exactly in that order . Any ideas ?

put `2, 3, 5` into *array*; generate *random index* of the array; return item by the index — Dmitry Bychenko, Sep 27 '18 at 13:05
place the 2,3,5 as array elements and generate the index at random using your random function with 0 as low and 2 as high. — Aswin, Sep 27 '18 at 13:05
Use an array like: `[2, 3, 3, 5, 5, 5]` and pick a random index. — , Sep 27 '18 at 13:05
const array = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]; const shuffledArray = array.sort((a, b) => 0.5 - Math.random()); — Vitalik Jimbei, Nov 17 '22 at 14:21

function random(numbers) {
     return numbers[Math.floor(Math.random()*numbers.length)];
}

Then you can call it with a list:

random([2, 3, 5])
