You can split on the comma and use map along with the unary plus operator to convert each element to a number.

str.split(",").map(a=>+a);


const str = "1,2,3,4";
const arr = str.split(",").map(a=>+a);
console.log(arr);

  • @The_Duck_Lord No problem. – Unmitigated Jun 10 '20 at 23:22
  • did it. Also found other ways of splitting strings that are not numbers into arrays with the [spreadSyntax](https://stackoverflow.com/a/33233956/2864502) though this one is used for splitting letters in a string. Like `hello` to [`h`,`e`,`l`,`l`,`o`] . – Elle Jun 11 '20 at 12:23
