How to remove any number characters from a string

Question

This is my current attempt which is not working:

  const word = "abcd123";
  const filteredNum = word.split("").filter((e) => Number(e) !== NaN);
  console.log(filteredNum);

Answer 1

Try this:

const word = "abcd123";
const result = word.match(/\d+/)[0];

console.log(result);

Answer 2

using isNan() function

    let word = "abcd123";
    let filteredNum = word.split("").filter((e) => !isNaN(e));
    console.log(filteredNum);
    console.log(filteredNum.join(""))
