Javascript Regex, replace just once

Question

Here is one example of what I need.

If I have some text like this one:

var string = "This is some test string for some my test.";

Then I have Regex like this one:

var patern = new RegExp("\\bsome\\b", 'gi');

and then line for replace:

var new_string = string.replace(patern,"replace_string");

This line above will replace all words "some" in string with "replace_string".

 new_string = "This is replace_string test string for replace_string my test."

What I need is to limit it to replace it just once. Is that possible, and how?

Don't supply the "g" flag if you don't want to do a global replace. — Pointy

Don't pass 'g' (global) as the second argument in the regex, maybe try something like str.replace(pattern); or str.replace(pattern, 'i'); to keep ignoring case.

'This is some test string for some my test.'.replace(/\bsome\b/, 'replace_string'); 
// => "This is replace_string test string for some my test."
