How to quote a regular expression?
I find a substring in the text and I want to not just replace it with another using replace, but use the found expression as an argument and frame it in quotes.
How to do it?

Answer 1

const textConst = "Hello world";
const re = /(.l.)/g;
const newText  = textConst.replace(re, '**$1**');
console.log(newText)
