Fixing the issue I raised and updating to node 18

JS - random tests can generate "0-length words" leading to words separated by more than 1 space.

Possible solutions:

• Don't generate empty words
• Add to description that there can be more than 1 space between words and how they should be handled

i hate Regexp, but is very friendly in cases like this

With JS. I tried to split with regexp. But it doesn't work. Very strange.

I dont even know what I am looking at

JS - random tests can generate "0-length words" leading to words separated by more than 1 space. I think that such inputs shouldn't be tested, but I haven't checked other languages.

In what language?

I've passed all tests. Also i passed random tests but i got an error "Cannot read property 'toUpperCase' of undefined". How it can be?
