Regular expressions tailored for a precise format in JavaScript

Is it possible to create a regex that can validate a specific format?

Answer №1

If you're looking to validate version numbers, consider using this regular expression:

/^v\d+(\.\d+)+$/i

Using this regex pattern will successfully match version numbers like:

  1. v1.0
  2. v1.12.13
  3. v1.0.1.0.1.0.1

and so on.
