getting number from string using regex

im wondering how I can get the number from the following string using regex

<@!1912983319>

I need the number inside of <@!>

i use const regex = /<@!(\d{17,19})>/g; i get to get <@3181> but unsure how to just get the number?

The number inside is just an example number, can be longer or shoter

>Solution :

Just remove(replace any non-number \d by empty string ''):

const num = "<@!1912983319>";
let number = num.replace(/[^\d]+/g,'');//1912983319
