General Tip

"The trick is to catch exceptions at the proper layer, where your program can either meaningfully recover from the exception and continue without causing further errors, or provide the user with specific information, including instructions on how to recover from the error. When it is not practical for a method to do either of these, simply let the exception go so it can be caught later on and handled at the appropriate level."

__invoke VS function VS Closure

This gist is about:

• https://twitter.com/Ocramius/status/600705252539691008

Mainly:

• function cannot (should not) be used when side-effects occur
