Issue with creating a Regular Expression from variable

Question

I am not able to create a regex from a variable, using template literals

What is wrong and how to fix it?

const myValue = 'a.b'
const reg = new RegExp(`/^${myValue}$/`);
/*
  /^a.b/
*/

Answer 1

Remove the slashes from the template literal. Slashes inside the string are escaped by the constructor, and included as part of the pattern.

const myValue = 'a.b'
const reg = new RegExp(`^${myValue}$`);
/*
  /^a.b$/
*/

console.log(reg);
