How to apply replacement on a string using regular expression dynamically JAVASCRIPT?

Question

I have this string and this regular expression. It matches hyperlinks FYI.

var str = "string https://www.pleasehelpme.com string";
var expr = "^(https:|http:|www\.)\S*";
var regex = new RegExp( expr  );

If I want to replace the Url by a constant string I should do this:

var myconstantstring = "https://www.thxforyourhelpcommunity.com"
var replaced = str.replace(regex, myconstantstring);
console.log(replaced);
// displays "string https://www.thxforyourhelpcommunity.com string"

But I want to replace the url in the string by the same url, surrounded by HTML tags so the result will be as follow:

"string <a href='https://www.thxforyourhelpcommunity.com'>clic here </a> string"

Is there a way to do it by getting the matchings table returned and replace it directly into the string? Obviously, I can acheive this by separating the process with multiple little steps but this is not what I'm looking for.

Thank you all.

Your regex is not defined correctly. Do you have `var expr = "^(https:|http:|www\\.)\\S*";`? Then, do you mean to replace the whole match with itself with tags added around the match? — Wiktor Stribiżew, Jan 14 '20 at 18:33
You are right, that is exactly what I meant @wiktor Stribizew. — ameliapond, Jan 14 '20 at 20:50
I thought you wanted `var replaced = str.replace(/(?:https?:|www\.)\S*/g, "Click here");`. — Wiktor Stribiżew, Jan 14 '20 at 21:34
I'm waiting for you to post your comment as an answer. Thats way I can accept it. Thank you very much. — ameliapond, Jan 14 '20 at 22:06
