Of course you can write everything yourself.  For any other than
trivial applications it's absurd though.  Plus, even for the small
ones using a lib which exists vs. coding yourself is often quicker.
As always, it's a matter of tradeoffs.

Btw, your code creates two copies of the input.  You could reduce
memory requirements by using String#gsub! instead of String#gsub.

Kind regards
