This video has honestly been the Regular Expression video that I've been looking for. The explanations are so quick and straight to the point, yet still detailed in information. Definitely saved me and my assessment this time round haha.

really useful video, helped me out a lot with zero experience with regex before. Thanks for making this, the internet smiles upon your kindness

Man, explaining that parentheses store captured data in variables was the most helpful part for me. I don't seem to remember any of the other regex tutorials I've watched in the past explain this.

Can you do a tutorial on RShiny app?

[@dataslice]

Yeah, I have a lot of topics I want to cover but RShiny is one of them!

[@dmytrobondarenko7169]

It would be cool if you could provide the sample text/numbers used in the tutorial in order to skip typing it out :)

Dear sir I am from India I am learning regex101 I watched your complete tutorial and I have successfully understood most of the part of regex Currently I've a text string of vocabulary words which has almost all english vocabulary letters(400k+) from which I wish to extract letters starting with m and must include j I know how to begin by writing ^m but if I want j to be included in my result anywhere in string with m letter starting. I don't want to specify "j" exact position and I want 8+ letters and with ending \w$ Sir please tell me how do I tackle this situation I tried alot but couldn't succeed sir please tell me code for this I am sorry for my rip english I am not good at english but sir I hope you can help me hoping for a positive reply asap 🙏🙏🙏

[@dataslice]

Maybe try ^m\w*j\w* for the first one
\w{8,} for the second
