The modern culture of Frameworks and Libraries has risen from the abyss when older technologies started to separate the functionalities into modules. Now, instead of supporting everything in the core language, the developers made it free for everyone to create libraries and frameworks that enhance the functionality of the core language. This way, the flexibility of the language has been increased dramatically.
MVC drastically reduces the time and efforts needed for building complex applications, as you need to focus on one area at a time (because DOM programming interface synchronizes the view and the model). As the View components are separated from the Model components, you can easily build reusable components for amazing and cool looking user-interfaces!
Angular 2.0 has recently been released, which claims to improve the performance of mobile, which is enough to convince new developers that this framework is high in development and updates regularly.
There are many users of AngularJS, including (but not limited to) Udemy, Forbes, GoDaddy, Ford, NBA, The Oscars, etc.
Similar to AngularJS, React is also an MVC (Model-View-Controller) type framework, however, it focuses entirely on the View components (as it was specifically designed for the UI) and can be seamlessly integrated with any architecture. This means you can use it right away for your websites!
It abstracts the DOM programming interface (and thus uses the virtual DOM) from the core functionality, so you get extremely fast rendering of the UI, which enables you to use it from node.js as a client-side framework. It was developed as an open-source project by Facebook with various contributions from other people.
If you have seen and like Facebook and Instagram’s interfaces, then you will love React. Through React, you can design simple views for each state in your application, and when the data changes, then it updates automatically. Any kind of complex UIs can be created, which can be reused in whatever applications you want. For the servers, React also supports rendering using node.js. React is flexible enough to use with other interfaces.
Apart from Facebook and Instagram, there are several companies that use React, including Whatsapp, BBC, PayPal, Netflix, Dropbox, etc.
It uses Model–view–viewmodel (MVVM) design pattern, which is slightly different than MVC in the sense that it has a binder to help the communication between the view and data binder.
For the fast server-side rendering of a DOM programming interface, it takes the help of Fastboot.js, so the resulting applications have extremely enhanced performance of complex UIs.
Its modern routing and model engine supports RESTful APIs, so you are ensured that you are using the latest technology. It supports Handlebars integrated templates that update the data changes automatically.
If you have ever used Laravel and NodeJS, then you will feel extremely comfortable using this Framework, as it combines the power of these both platforms resulting in an entity that looks incredibly professional, polished and yet sophisticated for any kind of modern application.
Many developers prefer SQL databases (due to their increased interaction with data and several other features) over NoSQL, so this is reflected in this framework, which makes it relatively more compliant with the standard and more accessible to the average developer.
If you are the part of any PHP community, then you must know about the Service Providers, thankfully, Adonis also has the same PHP like flavour in it, so you will feel at home using it.
Of all its best features, it has an extremely powerful routing engine which supports all the functions for organizing and managing application states, an error handling mechanism, SQL ORM for writing database queries, generators, arrow functions, proxies and so on.
I would recommend this Framework if you love to use stateless REST APIs for building server-side applications, as you will be quite attracted to it.
The attractive feature in this framework is that you can use selective modules with it for your specific needs. For example, you need to write simple HTML code, grab the JSON and create a Vue instance to create the small effects that can reused!
This framework can be easily integrated to any third-party template engine, however, by default it supports Underscore templates, which is the only dependency (along with JQuery), thus it is known for its extremely lightweight nature. It has the RESTful JSON interface with the support of MVC (Model–view–controller) design paradigm (that updates the front-end and back-end automatically).
If you ever used the famous social news networking service reddit, then you will be interested to hear that it uses the Backbone.js for several of its single-page applications. The original author of the Backbone.js created the Underscore templates as well as CoffeScript, so you are assured that the developer knows his stuff.
This framework provides models with key-value, views and several modules within a single bundle, so you don't need to download the other external packages, saving you time. The source-code is available on Github, which means you can further modify it for your needs.
If you are just looking for a startup framework to quickly build single-page applications, then this framework is for you.
