Angular JS Vs React JS: Top Factors that You Need to Consider
If you have plans to create a single page application, then you need to choose a good framework for front end development. Javascript is one of the most popular languages and developers love to build their applications or projects. AngularJS and ReactJS are frameworks that are super-fast, advanced and also widely adopted to create interactive single page applications.
Web and mobile apps are increasing in number every day and both ReactJS and AngularJS continues to be the top JavaScript Framework to handle websites that are of Medium to high complexity. A comparison between the two is still a popular topic in 2019 and both the frameworks are currently used by many news, travel and business companies in the UK, USA, France, Australia, Germany and etc.
What is ReactJS?
React is a Javascript library, which is developed by Facebook that allows the developers to build UI components. It assists in the creation of interactive user interfaces and also makes the codes easy to understand. The framework uses server side rendering for a performance oriented and flexible solution.
What is Angular JS?
This is a structural framework that helps to develop dynamic web apps and it lets the developers use the HTML as a template language and the HTML’s syntax to express the application’s components clearly and briefly. It is a fully featured JavaScript framework that assists the developers in creating dynamic, single page web apps and it also supports the MVC programming structure.
Implementation:
While comparing both ReactJS and AngularJS, it is important to know that ReactJS is an open source JavaScript library. So you need to add some external component libraries to have some features. You will have to add elements for routing to force unidirectional flows, set up tests, to call APIs, manage dependencies and etc.

AngularJS is a framework that comes with a large number of native features and options. It enables the developers to benefit from the number of options directly which makes it possible to start the project quickly without worrying much about the choices at startup. It is easy to implement.
The Learning Curve:
AngularJS development is a complete framework so developers who want to make an application on Angular, need to learn a lot of things like Typescript in depth and some other concepts to learn like directives, decorators, components, dependency, injection, templates and pipes. It also offers a lot of stuff, out of the box and it has strict coding that gives a clear structuring but the learning curve is steep.
ReactJS is simply a library and so it has a fewer concept to learn compared to AngularJS. So we need to know the syntax of JSK, manage the internal state, props for configuration, state management using Redux and etc. It offers great flexibility and doesn’t provide anything out of the box functions. Compared to AngularJS, it is easy to learn.
User Experience:
AngularJS development uses the Real DOM and this means that a developer can make any changes in the single data structure and the entire tree gets updated automatically. The feature is helpful in certain cases, but may be bothersome in many.
ReactJS uses Virtual DOM, which is the abstract form of Real DOM and makes it easy for the developers to make or update any changes that are initially performed by the end users. The changes made in the application do not affect the interface, which means that it serves various purposes like building highly dynamic UI that provides a great user experience.
Performance:
AngularJS has come up with hierarchical and highly improved dependency injection that enables the classes to be independent. This turns the result as external sources and offers high performance.
ReactJS on the other hand, uses Fiber that makes the library perform much better and this offers an edge when compared to AngularJS.
