JavaScript is a multi paradigm dynamic language that supports all of object-oriented, procedural, and functional styles of writing code. This makes it one of the most powerful, as well as the most misunderstood language of all times. Often one aims to write code that is modular, extensible, and testable. But not everyone is able to write good quality code because it requires deep understanding of the language, design principles, as well as discipline to write code that consistently follows a particular school of thought. Ember.js framework helps in creating applications which are highly modular, extensible, and can be tested easily, and the Ember object model lies in the heart this framework.
