... produces "baked" objects or functions. Initially, the purpose of this was because I believe Javascript's treatment of the this variable is atrocious, and I wanted to make it behave more like pretty much every OO language out there.
Additionally, I've created a version of the bakery for use with async.js. The modifications made are detailed in this blog post.
The bakery adds a couple of methods to every Function object you define:
- BakeConstructor()
- bake()
The first is the most useful method, and is meant to be used on constructor functions. It returns an alternate constructor that mimics the original constructor, but binds this inside every attached instance method (including prototype-inherited methods) with the just-created instance.
The effect of this is that nothing can change what this means for that particular object's methods. Additionally, storing the value of a method in a variable and calling it later will not have the (typically unintended) consequence of binding the global window object to this.
The bake method is pretty much identical to the bind method of other javascript frameworks, and returns a wrapper around the function with thisbound to whatever argument you pass in. This is nothing new (many other javascript frameworks provide it), but is provided for completeness.
Have a look in example.html for a concrete example.
