  • @Barmar, I'm sorry for my question, I was chased by the time, so I didn't have time to read about regex, I was a beginner in the regex. – Cuheguevara Aug 14 '18 at 03:09

Assuming that there will be atleast one such word, you can do it using String#match. The following example matches the words between parentheses.

console.log(
  "Hello (World) I'm Newbie"
  .match(/\(\w+\)/g)
  .map(match => match.slice(1, -1))
)

Rather than using a regex - use .split()...Note the escaped characters in the splits. The first split gives "World) I'm Newbie" and the second gives "World".

var str = "Hello (World) I'm Newbie";

var strContent = str.split('\(')[1].split('\)')[0];
console.log(strContent); // gives "World"

This might help you for your regex

  1. \w match whole world
  2. + plus with another regex
  3. [] starts group
  4. ^ except
  5. (World) matching word

var str = "Hello (World) I'm Newbie";
var exactword=str.replace(/\w+[^(World)]/g,'')
var filtered = str.replace(/(World)/g,'') 
alert(exactword)
alert(filtered)
