I am usually against Regex in general, things can get quite out of hand if one doesn't fully understand how it works and use it, especially if it passes tests (covering happy paths) and reaches production 😱.
But to answer the question, I personally have been in situations where I needed to Google to find something which was close enough to what I needed and then used a couple of online regex checkers to validate what I was writing. And I am one of those who believe it's really rare that you know everything about a topic. So even if I feel confident, I always do a bit more research (Google, find someone expert, use a tool, etc) ¯_(ツ)_/¯

Regex is a powerful tool, but as every Tobey Maguire fan knows: With great power, comes great responsibility.
