Joel. Thanks a lot for explain so easly and straightforward the way I see the modern and eficient programing.
Functional functions and pure Json object. No more data with methods. No more classes. No more if then. No more looping.
With functional programing, the functions names are necesary more important. The name must be a resume of the action.
The functions params must be less or equal than one on 90% cases.
Nice article Joel
