Regular Expressions are a mighty tool for word and text processing. They are not
just useful for programmers, but for anyone who wants a computer to recognize
patterns in strings. But a lot of people avoid them since they appear
complicated and have a steep learning curve.
If you are one of those people who have postponed learning regular expressions
because you just didn't know how to get started, this post is for you. Or, if
you already know and use regular expressions, but you want to check your
knowledge or deepen it, this post is for you too.
And really this post is quite short. If you want to learn regular expressions,
I recommend to take a look at [regexlearn.com](https://regexlearn.com/).
They also provide a [Cheatsheet](https://regexlearn.com/cheatsheet) for people
that are already familiar with regular expressions to quickly look up a specific
feature and refresh their knowledge. The best part is: it's all
[FOSS](https://github.com/aykutkardas/regexlearn.com)!
So if you want to finally acquire the ability to use REs, or know someone who
could benefit from doing so, maybe give it a try?
