change php regex to js regex text [duplicate]

Question

With this function I bold the text between **text**

function bold_text($string) {
    return preg_replace('#\*{2}(.*?)\*{2}#', '<strong>$1</strong>', $string);
}

Now I need to change it to js

function bold_text() {
    return preg_replace('#\*{2}(.*?)\*{2}#', '<strong>$1</strong>', string);
}

I tried something like var string=string.bold_text() but its not working

How do I change get bold text by using js?

Hope this will help you using replace()

const regex = /\*{2}(.*?)\*{2}/gm;
const str = `How **are** you Dan?`;
const subst = `<strong>$1</strong>`;
const result = str.replace(regex, subst);
document.write(result);

Using Function:

function bold_text(string) {
  const regex = /\*{2}(.*?)\*{2}/gm;
  const subst = `<strong>$1</strong>`;
  const result = str.replace(regex, subst);
  return result;
}

const str = `How **are** you Dan?`;
document.write(bold_text(str));

terrific. Do the regex var need to be between quotes?
