Cuando usar Call y Cuando usar Apply

En JavaScript uno de los temas mas importantes es el del manejo de contexto, es uno de los temas mas importantes cuando empezamos a hacer aplicaciones serias en JavaScript.

Dos utilidades muy importantes para el manejo de contexto son Call y Apply, ambas suelen ser bastante difíciles de explicar pero este video lo hace muy bien.

Para hacer un resumen del video, call y apply sirven exactamente para los mismo, setear el contexto en el que se va a ejecutar una function.

Call se utiliza cuando pasamos cada uno de los elementos de contexto como un parametro en la llamada y apply cuando queremos setear los elementos del contexto con un solo parametro que es un array que contiene los elementos del contexto a setear.
