AngularJS - MVC Architecture
Majority of javascript developers use AngularJs MVC pattern, because its offers architectural benefits over standard javascript.
It decouples the model and view which leads to effortless maintenance in the project.
Model
Model represents the current state of the application data.
Model is primarily concerned with business data.
Model consistently notifies its observers (e.g views) that a change has occurred so that views reacts accordingly.

ngInit
This directive is used to initialize the application data.
ng-init executes at priority level 450.
ngRepeat

Two-way data-binding
Two way data binding means automatic synchronization of data between the model and view components.
Whenever the model changes,angular will cause the view to automatically update leading to no explicit DOM (Document Object Model) manipulation and vice versa.
Two way binding example in AngularJS
<script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.3.14/angular.min.js">
</script>
<div ng-app="">

Description
The application fails to release (or incorrectly releases) a system resource before it is made available for re-use.
This condition often occurs with resources such as database connections or file handles.
Most unreleased resource issues result in general software reliability problems,
but if an attacker can intentionally trigger a resource leak, it may be possible to launch a denial of service attack by depleting the resource pool.
Recommendations
When a resource is created or allocated, the developer is responsible for properly... Eligible Object for Garbage Collection when all the references of that parent object explicitly assigning to null
Overview
JVM will reclaim the unused object from heap memory for future use.Unused Object means no longer referenced by any part of your program pointer to that object.
To demonstrate unused object is reclaim by garbage collector by calling System.gc() function.System.gc() method provides just a "hint" to the JVM that garbage collection should run.
But It is not guaranteed!!
Parent object set to null
If an object holds reference of another object and when you set container object's reference null, child or contained object automatically becomes... What is AngularJS?
Open Source Javascript Framework.
