Replace values between parentheses using Javascript and Regex [duplicate]

Question

I need to replace the text between two parentheses using Regex in Javascript. For example:

var x = "I need to go (now)";

I need to replace 'now' with 'tomorrow'. I tried this, but it didn't work:

x.replace(/\(now)\b/g, 'tomorrow');

You don't need Regex for such trivial problem. Use String's methods, as @anubhava suggested — hindmost

@anubhava does that replace all occurrences? I think it replaces only one — netgen

"I need to know (now)".replace(/\(now\)/g, 'tomorrow');

You don't need the \b and you need to escape the second ).

Does that replace all occurrences?

The code in my post will replace all occurrences because of the g flag at the end of the regex. Remove it to only replace the first occurrence.
