On verra aussi comment les outils modernes, de Chrome DevTools (maintenant amélioré avec l'assistant IA « Ask Gemini ») à Google Lighthouse,peuvent aider dans ce processus d'optimisation. Le but, c'est de te donner les moyens, en tant que développeur, de transformer une base générée par l'IA en une application web bien réglée et centrée sur l'utilisateur.
