Talking about the frameworks, they are basically a list of templates, that allow you to design and implement options related to the programming language, easily and effectively saving a lot of programming time and efforts, that will make the project finish smooth and good.

Much has been written comparing the use of, approach to, and completeness of these frameworks. But often overlooked are the metrics tracking the size, strength, and momentum of the communities and ecosystems surrounding these open source projects. These stats should play a key role in your selection.
