console.log('Hello World')
My solution was worse than most: replace one -> one1one You are only going to do the replace all for each number and if the "e" is also in eight it is still there for the next set of replace.
A better quick and dirty solution from Mastodon was to just add the common character first: twone -> twoone
The problem is that 21 is not the only problematic combination.
I was surprised seeing ton of people going for the replace approach. It didn't even cross my mind to edit the string, I went straight for regex for part 1 and it was easy enough to adapt it for part 2.
I did this exact thing and hit the point where it didn't work. I appreciated that the problem broke my code because it made me arrive at a better solution.
