The web development scenario is changing rapidly with new JS framework being developed every other month. It is quintessential to choose the best-fit JavaScript framework to deliver ambitious and competitive web apps. With plenty of framework options available, you may be spoiled for the choice of selecting the best one. However, as long as a framework can be used to build successful applications to meet your business, maintenance and performance goals, it doesn’t matter which one you have chosen as each framework has its own advantages and disadvantages.

JavaScript frameworks make it possible for your web apps to use an API just like any other program would on desktop, mobile, tablet or elsewhere. A front-end framework keeps the common parts of the page, like navigation, intact, while simply loading whatever new data the user has requested to provide to deliver better user experience.

Brief description of three popular frameworks

AngularJS by Google, React by Facebook, and Ember should be your choice if you wish to create the web apps that offer active communities and long-term support. Here, we will discuss the key features of these three frameworks in brief.

Angular JS

Angular JS is a comprehensive, open-source JavaScript framework that effectively solves the problem of single page application development by extending the functionality of HTML. JavaScript development services make your application up and run quickly. AngularJS uses TypeScript as default in documentation to validate open source projects to make them feel familiar and consistent. Angular JS focuses on simple modular code and test-driven development

AngularJS has good reasons to be the most popular framework from the perspectives of performance, native app support and server-side rendering. It is free from unnecessary complexity and takes a pragmatic approach to app development

Here are the key advantages of Angular JS for the developers

• It offers server-side rendering that speeds up initial page load time and makes dynamic pages crawl easily.
• Angular is the most popular framework and comes with easy to test codes.
• The framework allows for easy creation of personalized Document Objet Model (DOM) elements.
• Comes with dependency injection and simple routing.
• It is much faster as compared to previous version.
• Clean and precise UI design and alteration.
• Facilitates extension of HTML syntax and easily creates reusable components by directives.
• Data modeling is limited to the use of small data models which makes the code simple and easy to test.

AngularJS still remains the most popular client-side framework. It is written in TypeScript programming language by Microsoft which adds type checking and other enhancements to JavaScript. Some exclusive features make it the framework of choice for large enterprises.

ReactJS

ReactJS is an open-source JavaScript library that renders UI components very well. The Facebook powered framework focuses on amazing performance. It solves the problem of efficient rendering of large data sets that exist with other JavaScript framework. Besides providing awesome performance, it also facilitates server-side rendering.

Key features and advantages

• Simplified interface design and easy to learn API
• Good code reuse
• Fully component based architecture
• Easy importing of components due to little dependency
• Creation of universal web apps is possible due to server-side rendering
• Easy debugging of JavaScript
• Support for improving the performance of troublesome components

Ember

The framework combines lightweight sensibilities of open-source frameworks such as Backbone.js and Ruby on Rails with native frameworks like Cocoa. This allows for the creation of an open-source JavaScript framework that could be scaled up to accommodate the needs of a growing business. Ember makes it possible to dynamically render single page applications. The framework enforces strict rules for writing smart code so that the application can be easily scaled up.

Advantages

• Faster boot time and inherent stability
• Key-value observation
• Strong data layer that integrates well with Java
• Observers to change values which result in rendering the values being changed
• Friendly API and supports URL
• Minimizes DOM

If you prefer a framework for your JavaScript development services, then try out Angular as it provides a robust set of features that are all integrated. The framework has a robust CLI and provides Ahead-of-Time (AOT) compilation for production builds. It is used by numerous key apps inside of Google which provides it longevity. It supports several features like UI rendering, routing, data binding, testing, form validation and much more. The framework has a robust open source community and is run by a full-time team of Google.

React provides great performance, is easy to get started and quite popular as well. A robust open community and a full-time team of Facebook runs the project. It provides a lot of lightweight functionalities without the overhead of a framework. A smaller version of React, known as Preact is also available.

Use Ember if:

You have big plans for your app and you want to make your SPA right from the scratch. Even if your application is smaller, it offers faster boot time and inherent stability.

There are certainly several more frameworks and libraries that could be listed which the developers make use of to achieve some key objectives of front-end development. All libraries and frameworks have their own set of advantages and disadvantages, and all of them can be used to build small, medium and large applications for the use by enterprises. You can consider choosing a framework that could include a robust set of 3rd party functionalities as it will further help in boosting the productivity.
