Agree. Add the blank space and replace with the position could be in a single function

Great solution, but the second replace is not necessary.

I just love this solution, great work!
It's so elegant, and terse and clean with just string manipulation.
Awesome.

why (2) no for-loop?

.replace(/./g, c => c + " ")
.replace(/[a-z]/g, c => c.charCodeAt(0) - 96)

this is two loops just without a "for" syntax

Hahaha... :D :D This Kata is the Best! :)

When I was designing this solution I tried to keep these in mind:

1. no data conversions: string => array => string
2. no for-loop
3. no if-else statements
