Cuando un programador inicia a prender un nuevo lenguaje de programacion es muy tipico iniciar con el famoso “Hola mundo”, que no es mas que un simple ejemplo de un nuevo programa de computadora en donde aparece la leyenda “Hola mundo”.

 

Y aqui les dejo una pequeña compilacion para los nuevos programadores:

Suerte!
