mapfuncs

Collect result of each function for given arguments and context.

Usage

see test.js for examples.

API

Lists should be Array-like objects, or should be false-y, in which case they default to an empty list.

mapFuncs(funcs, args[, ctx])

Invoke each function in list funcs with arguments list args and context ctx, collect and return the results.

In case of just one function, you can pass it directly as funcs, no need to wrap it in a one-item list.

Together with the false-y default, this allows to use mapFuncs for a simple event subscriber model:

Blog.prototype.publish = function (post) {
  post.url = this.save(post);
  this.posts.push(post);
  mapFuncs(this.onpublish, [post, this]);
};

mapFuncs(funcs)

Return a proxy function that will pass its arguments and context to each function in list funcs and returns the collected results.

The proxy function will use the original list of functions (not a copy), so changes to that list will apply to the proxy immediately.
