React JS is a front-end library developed by Facebook. It is used for handling the view layer for web and mobile apps. React JS allows us to create reusable UI components. It is currently one of the most popular JavaScript libraries and has a strong foundation and large community behind it. It encourages the creation of reusable UI components, which present data that changes over time. Lots of people use React JS as the V in MVC. React abstracts away the DOM from you, offering a simpler programming model and better performance. React JS can also render on the server using Node, and it can power native apps using React Native. React JS implements one-way reactive data flow, which reduces the boilerplate and is easier to reason about than traditional data binding.

React JS allows developers to create large web applications which can change data, without reloading the page. The main purpose of React JS is to be fast, scalable, and simple. It works only on user interfaces in application. This corresponds to view in the MVC template. It can be used with a combination of other JavaScript libraries or frameworks, such as Angular JS in MVC.

What are the React JS Features?

JSX

JSX is JavaScript syntax extension. It isn't necessary to use JSX in React JS development, but it is recommended. In React JS, instead of using regular JavaScript for templating, it uses JSX. JSX is simple JavaScript which allows HTML quoting and uses these HTML tag syntax to render subcomponents. HTML syntax is processed into JavaScript calls of React JS Framework. We can also write in pure old JavaScript.



Components

 React JS is all about components. You need to think of everything as a component. This will help you maintain the code when working on larger scale projects. Components let you split the UI into independent, reusable pieces, and think about each piece in isolation. Conceptually, components are like JavaScript functions. They accept arbitrary inputs (called “props”) and return React JS elements describing what should appear on the screen.


Unidirectional data flow and Flux

React JS implements one-way data flow which makes it easy to reason about your app. Flux is a pattern that helps keeping your data unidirectional. In React JS, a set of immutable values are passed to the components renderer as properties in its HTML tags. Component cannot directly modify any properties but can pass a call back function with help of which we can do modifications. This complete process is known as “properties flow down; actions flow up”.


React Native

React JS has native libraries which were announced by Facebook in 2015, which provides the react architecture to native applications like IOS, Android and UPD. React JS is licensed under the Facebook Inc. Documentation is licensed under CC BY 4.0.


Virtual Document Object Model

React JS creates an in-memory data structure cache which computes the changes made and then updates the browser. This allows a special feature which enable programmer to code as if whole page is render on each change where as React JS library only render components which actually change.



React JS Advantages

  • Simplicity React JS is just simpler to grasp right away. The component-based approach, well-defined lifecycle, and use of just plain JavaScript make React JS very simple to learn, build a professional web (and mobile applications), and support it. React JS uses a special syntax called JSX which allows you to mix HTML with JavaScript. This is not a requirement; Developer can still write in plain JavaScript but JSX is much easier to use.
  • Easy to learn Anyone with a basic previous knowledge in programming can easily understand React JS while Angular and Ember are referred to as ‘Domain specific Language’, implying that it is difficult to learn them. For React JS you just need basic knowledge of CSS and HTML.
  • Native Approach React JS can be used to create mobile applications (React Native). And React JS is a diehard fan of reusability, meaning extensive code reusability is supported. So at the same time we can make IOS, Android and Web application.
  • Data Binding React JS uses one-way data binding and an application architecture called Flux controls the flow of data to components through one control point – the dispatcher. It's easier to debug self-contained components of large ReactJS apps.
  • Performance React JS does not offer any concept of a built-in container for dependency. You can use Browserify, Require JS, EcmaScript 6 modules which we can use via Babel, React JS-di to inject dependencies automatically.
  • Testability React JS applications are super easy to test. React JS views can be treated as functions of the state, so we can manipulate with state we pass to the React JS view and take a look at the output and triggered actions, events, functions, etc.


 React Limitations


  • High pace of development

The environment constantly changes, and developers must regularly relearn the new ways of doing things. Everything is evolving, and some developers are not comfortable with keeping up with such a pace.

2. Poor documentation

The problem with documentation traces back to constant releases of new tools. Different and new libraries like Redux and Reflux are promising to accelerate the work of a library or improve the entire React ecosystem. At the end, developers struggle with integrating these tools with ReactJS. Some members of the community think that React technologies are updating and accelerating so fast that there is no time to write proper instruction. To solve this, developers write their own documentation for specific tools used by them in current projects.

3. ‘HTML in my JavaScript!’ JSX as a barrier

ReactJS uses JSX. It’s a syntax extension, which allows mixing HTML with JavaScript. JSX has its own benefits (for instance, protecting code from injections), but some members of the development community consider JSX to be a serious disadvantage. Developers and designers complain about JSX’s complexity and consequent steep learning curve.
