Apologize if the title of the question is misleading. Actually I am looking for the javascript equivalent of the following python code:
## python code
def call_with_context(fn, *args):
## code to create context, e.g. profiling, db.connect, or drawing context store stack
fn(*args)
## code to close context
This implements the similiar functionality as the "with statement" in python, which implements the aspect-oriented paradigm.
So my question is what is the javascript way of doing such things? I have seen some code using Array.prototype.slice(arguments, 1) to do so, but I don't know if this is a common pattern in javascript, or there are better patterns supported in javascript (e.g. by closure) so ppl don't really do that. Pls also correct me if I am using the wrong keywords, because I really dont know how to refer to my problem with a better name than sandwich.
EDT 1: And I appreciate if someone can explain how to return the result of fn(*args) from inside the wrapper call_with_context. thanks!
