Abstract:

One of the pitfalls of using a JavaScript framework, especially among beginners, is the ability to quickly lose sight of what is specific to the framework, and what is specific to the core JavaScript language. However, as bandwidth constraints continue to dissolve, and browser compatibility issues erode, it makes sense to consider a framework on each project. Whether or not you actually use a framework after these considerations are made, is totally up to you.
