Split string by all non-numeric characters

December 7, 2022

I have a string like this:

let s = '10p6s23'

I’d like to split it in such a way that I get the numbers and the letters in an array, so ideally I’d get this:

 [10,'p',6,'s',23]

The ultimate goal is to build a add/subtract calculator where p = + and s = -. So the string above would resolve to 10 + 6 - 23 = -7.

What I’ve tried

Split string into array on first non-numeric character in javascript

This worked well, except it only split on the first char, not all chars.

>Solution :

const regexp = /(\d+|[a-z]+)/g;
const str = '10p6s23';

const array = [...str.match(regexp)];
console.log(...array);

let replaced = array.map(item => {
  switch(item) {
    case 'p':
      return '-';
      break;
    case 's':
      return '+'
      break;
    default:
      return item
  }
}).join('');

console.log(eval(replaced));
