re: The Power of the Observer Pattern in JavaScript VIEW POST

re: This is good for other languages which do not have event support, why would this be better than using EventTarget api?

I agree. This demonstration of the observer pattern suits languages other than JavaScript for broadcasting events, and is a great exercise in building out the pattern for oneself. But given that JS is an event-based runtime, much of the code here essentially reimplements parts of the event loop, but doesn't have the same depth of performance optimizations as the language builtins do
