    It really depends on what you want to achieve. Please provide an example input and the desired output. "But this is not working..." is not a useful problem description. – Felix Kling Jul 26 '21 at 11:20

  • I need to remove everything from the value except the spaces and the rub submbol ₽ –  Jul 26 '21 at 11:23
  • if you want to remove everything bar the spaces and ₽ - what's the deal with `0-9`? you want to keep numbers as well? – Bravo Jul 26 '21 at 11:27

[^0-9₽] means "NOT 0-9 or ₽".
To remove everything but keep spaces and ₽ do:
.replace(/[^ ₽]/gi, ''))

let string = "h 3 l l 0 ₽ h 4 l l 0";

console.log(".replace(/₽/gi, '') Will remove ₽:")
console.log(string + " > " + string.replace(/₽/gi, ''));
console.log(".replace(/[^0-9₽]/gi, '') Will remove everything that is not 0-9 or ₽:")
console.log(string + " > " + string.replace(/[^0-9₽]/gi, ''));
console.log(".replace(/[^ ₽]/gi, '') Will remove everything that is not SPACE or ₽:")
console.log(string + " > " + string.replace(/[^ ₽]/gi, ''));
