It's a cool presentation. Careful, however, this only teaches a specific variant of regexes (the PCRE ones). Those are common, but expressions like "\d" won't work in grep, sed, or many other tools. I wish it had noted the variances.

#12I'm not a RegEx expert, but I've googled them enough to have the basics. This is exactly what I needed to improve my skills.

#16Not to sound dismissive, but virtually everyone, who knows what are regular expressions, knows this. Only last, 15th, lesson starts to touch on things that are arguably not common knowledge - word boundaries and back references. Look aheads and look behinds, the parts which most people struggle with, aren't covered at all.

#17Thanks for sharing. Hope it helps some people out.
I took a look at it and have a small nitpick: you refer to the '\' character as "slash". See Lesson 2 for example.
Cheers

#19This is one of the best online learning experiences I've ever had. I went through it twice and never felt uncomfortable with regular expressions afterwards. The author also does this for SQL, which I haven't tried: https://sqlbolt.com/ Are there any other online learning courses like this?
Agreed. Went through it twice and that combined with a bit of real-world practice made me pretty proficient at RegEx.
Fantastic site.
