Replace all left spaces with a specific string

Question

I have following code to replace left spaces with a specific string but, It is not working as I want.

Answer 1

You may use a lambda function as 2nd argument of .replace:

const s = '  asdadasdad as asdasd asasd';

var repl = s.replace(/^\s+/, m => m.replace(/\s/g, 'x'));

console.log(repl);
