Hello! New to this forum!
Can you please give your opinion?
The difference is that front-end frameworks provide solutions for view-layer only (e.g. AngularJS), while backend frameworks provide solutions for both view and model layer (e.g. Java Spring framework). These layers are clear in MVC Web applications, where they're mapped to controllers, views and models/domain objects respectively. Frameworks come with their own set of tools and utilities, providing solutions for problem domains at different levels of abstraction.
