@ekaitz_zarraga TS, same thing.

Wrote an implementation of the function that groups objects in an array in modern #javascript. Definitely one of the essentials.

The only thing I miss is the "where" statement from Haskell, so I don't have to repeat myself when writing functionally.

0. Naming artifacts
1. <Item unavailable>
3. Off by one errors.

The three hard things in #cs are:
1. Naming things
2. Cache invalidation
3. Off-by one errors

With #fp:
1. The functions' type signatures reflect all that they do, so you don't have to worry so much about names.
2. Cache invalidation is handled centrally in the runtime.
3. Higher-order recursive patterns provide a way for you to do your job without using indexes, so off with off-by-one errors.
