OMG!!!
I write 13 lines to achieve this.

Well dang.

a little hard to read, although the idea is simple

maybe there should be a simpler way to write regex

thanks for the explanation

if I understand correctly, this only works if the word is followed by a space or the end of the string, if you put a comma after the word, then it no longer works

I'm familiar (not expert) with regular explressions and this is hard to read.

You could say "get familiar with X concept and then it will be easy" for anything that is considered hard for the average person.

Best practice means best for the average person.

it's readable if you understand regexp.

You're not dumb. It's just another notation that a lot of languages have incorporated. Super useful, but if you haven't invested the time to learn it, you could hardly be expected to know it any more than you could be expected to know Ancient Greek, if you'd never studied it.

It's not that hard to read, if you're familiar with regular expressions. I recommend getting familiar, they are pretty useful.

What I see;
Wololoooo

Hard to read code is not best practice.

It is worth it. But chiefly in certain self-contained and exceptional scenarios:

1. Search and search-and-replace operations in code editors, terminals, databases, and spreadsheets.
2. Code that will never need to be shared or debugged, such as one-off automation scripts or data extraction/manipulation.
3. A proven performance improvement achieved by the RegEx engine to widen a particular performance bottleneck in an app or database query.
4. Scenarios where the readability/debuggability trade-off when compared to the alternative code is a wash, such as can easily be the case in complicated spreadsheet formulas.
5. CodeWars katas. 😉
