'9 JavaScript Design Patters You Will Love' javascript designpatterns
s will point to the same function, the same piece of code.Despite being object-oriented, JavaScript does that in its own peculiar way. Because it does not have proper classes, it also can not limit access to a class’s components. On a language as Java or C++ you can define the access rights for a class’s members , but being the clever little thing it is, JavaScript has a way to emulate this behavior.. A closure is a function with access to its parent’s scope, even after the parent has finished.
The greatest utility of this pattern is to make a clear separation between the public and private parts of an object. If we have a private function referencing a public function, we can’t overwrite the public function. The private function will keep pointing to private implementation and it will lead to bugs.
The emitter will execute all the operations to which the observers are subscribed. Those operations can be, subscribe to a topic, unsubscribe from a topic, and notify subscribers every time something is published to a topic., which is the one we will see in this text. The same way in real life, a mediator is an object that will be the focal point of communication between other objects.
The obvious benefit from this pattern is the improvement in communication between the parts of the system. In the same way, it happens in a debate, the mediator assures that each person has time to speak and no one speaks out of order.
