There were so many good creators on there and hearing New Boston on the list brought back all my memories of first learning web development from his channel. I also want to give a huge thanks to your for your channel. I have learned a ton from you and your channel was one of my biggest inspirations for starting my own channel.

This is a really compact, concise video covering everything you need about regular expressions. I'm very experienced with regular expressions, but came here to get more info about look ahead and look behind, and you described those in a way that is much more meaningful than anything else I've run across online. Truly great work.

I'm so grateful for your JS videos. Sometimes i get stuck on documentations for over an hour without any understanding of the content, then I come here and everything seems so clear. Keep up the awesome job!

In my long experience, I find that everybody learns regex every time they use it. Even if you look at perfectly reasonable regex 3 weeks after writing it, it's alien script.

This is so true. 2 months ago i learned regex a bit , but now i dont even know how to validate a phone number. I Copy pasted email validation somewhere and boom. Done. I think its more important to know what regex can do and knowing when to use it. Not actually how to write that code. Thats my opinion cause if ur not using it regularly then u will forget about it in 2 weeks.

Very concise tutorial. Covered many aspects of Regex and explained in easy to understand layman terms in a compact 20 minute session yet not omitting key details. Thank you very much for sharing your knowledge.

This is an excellent tutorial. It is a very clear explanation. I will ask all of my programming friends who shy away from regex to watch it. I've been using regex for decades, and I still have trouble with look-ahead and things like that. I always have to refresh my memory after I stop using it for awhile. After watching this video I feel like I understand the entire concept much better. Thank you very much.

This is the best Regex video I've ever watched. Bravo to you sir for breaking this down. Easily one of the most confusing aspects of programming in my opinion.

Really an unbeatable example of how to convey information. This guy is clearly intelligent and can plan and execute, good job and thanks for the video

Wow, thank you so much. I'm working on a really complex algorithm that needs to use regex, but I have had such a hard time understanding it until now!

Excellent! This was a perfect summary of regex which I really needed. Just used it in some Google Apps Scripts I'm writing and it has made a huge difference in my ability to pull specific links from XML code. No more depending on importXML function to find matches. I had learned this in college about 15 years ago but never applied it so this was a life saver. THANKS!!!

I compared your video with others. In 20 minutes, you explained the most important concepts clearly. Thank you, save our time and our life. You are a very smart tutor.

I'm amazed how calmly and thoroughly you're explaining everything... Great work, I managed to write the regex I needed, thank you!

Naming capture groups is more important than you think and is a good habit to get into early. In JavaScript you can reference these names as object keys which gives so much more clarity to your code.

Great info. Regex seems so daunting at first but once its broken down well like this, it becomes much easier to understand.

I've used RegEx for about 20 years now...used it in PERL, C++, VBA (Word), Bash, Python....even inside apps like Alteryx and Talend!! I've given so many impromptu classes to try and help folks understand the real power of RegEx. It is ridiculously powerful! Thank you for this vid...more information out there to help people is a good thing! Cheers!!

This was so well made. Easy to understand but very detailed. Thanks a lot!

Great info in a short amount of time, I was strugling with building complex regexes and this helped a lot!

Learning RegEx is one of the best skills I’ve ever learned. I use it extensively for prepping text for other uses, renaming files, especially music files, in programming, etc. Invaluable. Learn RegEx.

i always had a love hate relationship with RegEx in my .net projects. i prefer simple logical coding to find a string patern.. but eventually it becomes a huge chunk of ifs and cases and includes... and i keep getting not perfect results... but is easy to write from scratch and read.. and then you have regex... you take hours to make the "search pattern" you keep googling and trying deferent online tools, and after that is a single line of code usually and work so much faster and has better results..but you cannot understand wtf it says after you revisit it few months later... 🙄🤣🤣🤣🤣

That's why you simply put a comment above the RegEx explaining what it does. It's much easier to understand something if you know what its overall purpose is. If you really need to, you could also explain each individual portion of the RegEx, but that's often unnecessary.

Which is encouraging/motivating because I can see the light at the end of the tunnel.
