C'est aussi ce que je pensais avant d'apprendre à remanier. Aujourd'hui, j'ai une base de code de production vieille de 10 ans qui est meilleure aujourd'hui qu'elle ne l'était lorsque je l'ai créée. Je détesterais revenir en arrière : chaque année, c'est tellement mieux que l'année précédente.
C'est grâce aurefactoring que cela est possible. C'est le processus qui consiste à modifier la conception de ton code sans changer son comportement.
