doesn't work anymore

Mad Doctor!

The input will always be in lowercase and never be empty.

Won't happen.

the code won't work

what if A string is given in uppperCase

There's no type coercion in string > string.

Would it be good practice to convert to a number if you plan on working with TypeScript or if you don't want type-coersion related bugs in your code?

Thank you for the comments.

It really makes it a lot easier to understand without having to google everything first.

Still gonna google it to get the finer details, but I don't have to before I can understand what's happening.

The string comparison is comparing the first digit, and 5 is greater than 1, so it terminates the comparison. If they were equal it would proceed to the next digit.

There is only one argument there. It's the one inside the parentheses. And the method is applied to a string. There is an implicit coercion to integer from string involved.

Haha, same, good to know :D

If there is equality, it's a "touch", not a "collision".
