Summary: Decorators are functions called on classes, class elements, or other JavaScript syntax forms during definition that provide for a metaprogramming capability in JavaScript. This proposal recently reached stage 3 at TC39. Prototyping it in SpiderMonkey will provide valuable feedback to the TC39 committee and ensure our implementation does not fall behind the standard.
