You can build things in JavaScript. You can ship them. You can make them work. But when someone asks you to explain what your code is doing, the words are not there, and neither is the understanding that would produce them. You learned by imitation. This book teaches you what you were actually doing.

The ultimate guide for software architects. Master the 'Configuration over Programming' philosophy and accelerate your PHP development with Ragnos and Artificial Intelligence.

El manual definitivo para arquitectos de software. Domina la filosofía de "Configuración sobre Programación" y acelera tu desarrollo en PHP con Ragnos y la Inteligencia Artificial.
