Framework environment is a complex system that is used for back-end development and front-end rendering of a mobile application. It includes toolsets, compilers, debuggers, apps and different libraries that offer many helpful resources to developers. It is a base of the future applications that can save a great deal of time and resources, and understanding the differences between different frameworks and their pros and cons is essential to finding what works for your business. We have been working in this area for many years and have accumulated great experience in it while developing mobile applications as parts of bigger solutions. We found frameworks to be a great investment that, if chosen correctly, goes a long way.
