I'm trying to write a RegExp in GoogleScript. The expression I have written seems to always return null.

It works fine in online RegExp testers.

  var number = '(123) 456-7890';
  var regExp = new RegExp("/\(\d\d\d\) \d\d\d-\d\d\d\d", "g");
  var a = regExp.exec(number);
  Logger.log(a);

Try to use a literal regexp instead: `var regExp = /\(\d\d\d\) \d\d\d-\d\d\d\d/g` – some Sep 15 '19 at 22:43
Thanks. Got it working with this: `var number = '(123) 456-7890';` `var regex = /\(\d\d\d\) \d\d\d-\d\d\d\d/;` `Logger.log(regex.test(number));` – SKS Sep 15 '19 at 22:48

Could be simplified as `/\(\d{3}\) \d{3}-\d{4}/` – TheMaster Sep 15 '19 at 23:00
Does it require a closing forward slash too i.e. /someregex/? – hoipolloi Sep 16 '19 at 02:29
