Cher @Effey46, j'ai le plaisir et l'honneur de vous annoncer que vous n'avez PAS gagné le concours MOVAI CODE. Ce qui fait de vous un EKSSELAN Codeur.

SPOILER : j'espère qu'on aura le plaisir de recevoir votre participation à l'episode 2 du MOVAI CODE (stay tuned).

Bravo toutefois pour votre belle contribution 😊

Je fais un peu de ménage dans les issues -> d'ailleurs go participer à l'édition 5
