Beside logic, regex is a powerful tool to put things into order. If possible we would like to expect more regex tutorials to be released. Your tutorials do make a great difference in our life. As always, thank you for providing this insightful introduction of regex.

Another super clear tutorial, Steve! Thank you, regex is really tough to get a handle on and this helps.

Thanks. Your video was quite helpful. I was racking my brain over some data that I downloaded into R and then used the tidyr package to split up a messy date column. The only way was to use regex. tidyr has a function that works with regex namely separate_wider_regex(). You feed a regular expression pattern into it to split columns. Even though regex looks a bit different in R than in javascript your video was still quite helpful.

Thank you! Really informative video. Challenge! Make an input for email address which would validate input on each letter and would not allow to enter the wrong match.

This is great thank you. Would have loved to also have that address example uploaded so I could play with it to see if I could complete it before you go through it all. Of course, I could type it out but I'm lazy like that.

Griffith, first I wanted to say I love your channel and it helps me immensely, thank you. Secondly, I would like to ask for your advise. I find that sometimes I have difficulty with programming logic especially when it comes to those common challenges suck as in HackerRank. Do you find those a good measure? How could I improve my logic?

What exactly do the ( ) do in a reg ex? (Parenthesis). Kind of confused by this. Do they create “sub expressions”. Please explain. Thank you
