Lol what? He used sort which is a built in function, also his solution is O(nlogn) when the optimal solution is O(n)

I thought of almost the same solution

smart

I mean you are not wrong...

I think he noticed that but he just sacrificed performance for compactness

him: making the solution longer by adding turnary operator

watch web dev simplified tutorial it helped me understand regex a lot

Thanks mate really needed this!

you can also get rid of the last semicolon :))))))))))))))))))

it can get more compact if you turn it into an arrow function

this is better practice because in real life cases you might wanna change the letter "r" into something else...
and in his solution just changing the letter "r" will do it...

or he just used js obfuscator
