• 2 use the Number.prototype.toString method - I'm curious, what IS the method shared on W3school? Knowing W3school, it's probably wrong - I would avoid that site like the joke it is, and get better documentation form MDN – Jaromanda X Commented Jan 7, 2023 at 3:23
• personally, I always use toString since you can specify a radix – Jaromanda X Commented Jan 7, 2023 at 3:38

All of these will work:

`${num}`
num.toString()
'' + num
String(num)

Seems that var str = '' + num is the fastest way to convert a number to a string (num being the number variable).

let num = 5
var str = '' + num

(results based on this benchmark: http://jsben.ch/#/ghQYR)

You can use the built in function: toString():

Example:
let number = 3
let stringed_number = number.toString()

I remend using .toLocaleString if you want pretty formatting, like mas or periods for grouping.

However if you know you don't want pretty formatting you should use .toString
