ChatGPT is a regex god

ChatGPT can give you statements that either:

1. Sounds very truthful, but has something wrong with it
2. Is surprisingly good and accurate

With Regex questions, it seems to weigh way more on the latter.

A few examples:

1. Match a Reddit post URL
   

2. Match a Twitter reply
   

3. Match a document format from a country
   

4. Match any email address that ends with "gmail.com" and contains a plus sign (+) followed by any combination of alphanumeric characters before the @ symbol
   

5. Match any phone number in the format (XXX) XXX-XXXX where the first three digits cannot be 555
   

Be careful, it's prone to mistakes, so it's always a good idea to test it on an app like https://regex101.com/

Overall, I feel like most of the generated regular expressions are already going to be good enough to save some valuable minutes of your life.
