About the Book

Existen muchos lenguajes de programación, algunos de ellos con un propósito específico y otros con propósitos más generales e inclusive se habla de lenguajes de programación para la Web; por lo tanto, este libro está dirigido a personas con conocimientos generales de programación y conocimiento básico de la sintaxis de JavaScript u otro lenguaje ANSI C como: Java, PHP, etc., que quieran introducirse en el mundo del desarrollo Web, específicamente del servidor con Node.js, con un lenguaje de propósito "general" como JavaScript. Pero también personas que han trabajado JavaScript del lado del cliente, ya sea simple vanilla JavaScript, librerías y/o frameworks, y quieran aprovechar ese conocimiento que tienen del lenguaje JavaScript para utilizar en el servidor.
