I have the following string:

"h3. My Title Goes Here"

I basically want to remove the first 4 characters from the string so that I just get back:

"My Title Goes Here".

The thing is I am iterating over an array of strings and not all have the h3. part in front so I can't just ditch the first 4 characters blindly.

I have checked the docs and the closest think I could find was chomp, but that only works for the end of a string.

Right now I am doing this:

"h3. My Title Goes Here".reverse.chomp(" .3h").reverse

This gives me my desired output, but there has to be a better way right? I mean I don't want to reverse a string twice for no reason.

I am new to programming so I might have missed something obvious, but I didn't see the opposite of chomp anywhere in the docs. Is there another method that will work?

Thanks!
