match_digits.js

const text = "item42";
const match = text.match(/\d+/);
let digits = "none";

if (match) {
  digits = match[0];
}

console.log("text=" + text);
console.log("digits=" + digits);

match-digits `match` returns details about a pattern match. Reading the first entry gives the text that matched the whole pattern.
