axios random url picking

I just wonder how to pick random URLs to performed an axios post request.

I have three servers I want to pick randomly from

let one = "http://127.0.0.1:8000/middle/server_js/"
let two = "http://127.0.0.1:8001/middle/server_js/"
let three = "http://127.0.0.1:8002/middle/server_js/"

currently is using only one:

let req = await axios.post("http://127.0.0.1:8000/middle/server_js/", body, {

I just want to choose random port from

Example of a solution via an array

// Defining an array
var arr = ['adress1', 'adress2', 'adress3'];

// Getting a random array key
var rand = Math.floor(Math.random() * arr.length);

alert(arr[rand]); // "adress2" for example
