What is React?
It is a declarative and highly accurate library that provides reusable code, which enhances the efficiency and flexibility of single-page applications.
Key Highlights of React
- The component-based, front-end library optimizes the page loading speed and efficiency of single-page applications.
- React helps in generating easy-to-use interactive UIs.
- It is used to design comfortable and interactive views for every state in the application.
- It offers on-time updates that help users to receive relevant components required when data changes.
- React breaks the UI into smaller individual components, enabling users to simultaneously work on each component resulting in faster app development.
Why does React have the edge over other frameworks?
React has a lot of efficient features that make the library stand out against other libraries. The following is the list of powerful features that have catapulted React to the numero uno position:
- Effective DOM Manipulation
DOM (Document Object Model) is a crucial part of the web application, as it represents the web page of a document, generally HTML. DOM manipulation has become the latest trend in modern applications as they require numerous animations, state transitions, impactful effects, and so on:
The Virtual DOM is a virtual model of the actual DOM tree with each branch ending in a node that contains objects. The feature enables the users to update only the necessary parts of the DOM tree instead of re-rendering the entire UI.
The whole process of implementing a virtual DOM is faster as it stays only in the memory without providing access to the user.
- More functionality with lesser code
- Quick application development
Components are the foundation of any React application. Most apps require a lot of components to control each task in app development. React components have a wide range of logic and controls that can be reused because of which the applications can be developed at a quick pace.
- Easy error debugging
In React, the child components are placed inside the parent components, and so the data flows only in one way. The single direction of data enables the app developers to identify the exact location of the error in an application resulting in faster debugging. React components are designed based on the Separation of concerns principle, according to which a computer program is separated into smaller sections, each of which addresses different issues.
- Use of UI component library
A set of ready-made components that provide the necessary blocks of code for developing apps constitute the UI component library. The use of the UI library, Kendo React, brings in a lot of advantages like greater compatibility, better accessibility, speed, and easier handling.
For instance, the Create React app is used at the beginning stage of React app setup. This enables the developers to start using the React app with a single command.
Redux is a popular state management library used in React. It places all the data inside a store such that each component has access to the store. The two powerful concepts of Redux are actions and reducers.
Actions are the events that transfer the data, and reducers are functions that perform a task corresponding to the data and return it to a new state.
- Easy to learn
- Use in developing mobile apps
React is known for its effectiveness in web application development but is not limited to only that. React Native, an immensely popular framework of React helps in developing mobile applications.
- Chrome extension to debug React applications
Facebook has come up with a chrome extension that is exclusively used for debugging React applications. This makes debugging simpler and faster.
In addition to this, React does not insist on strict code conventions or file organizations, unlike other frameworks. This helps developers to have their convenient conventions and use React in any way they like. React can be assigned to handle a single button, a few interface pieces, or an application’s entire user interface.
Prerequisites for learning and using React
The following list will help developers who have just started using React determine if they are ready to take the plunge:
- Understanding of how Node Package Manager (NPM) works: A basic understanding of installing packages using NPM, finding required software from the NPM registry is indispensable for developing React apps.
React Vs. Angular and Vue
Angular, developed by Google in 2010, is a TypeScript based framework. Two versions of the same were released in 2016 (Angular 2) and 2020 (Angular 11).
Vue, a.k.a Vue.js, was released by Evan You in 2014. The latest version of Vue was released in September 2010 (Vue 3.0), which has its own GitHub tool.
Let us compare the key aspects of the three frameworks.
|Year of release||2013||2010||2014|
|Leading companies using the framework||Facebook, Uber||Google, Wix||Alibaba, GitLab|
|Number of Contributors||1533||1352||382|
|Number of jobs in LinkedIn||70963||72747||11590|
Future Scope of React in the Industry
With growing patronage from new-age developers, React has become a top trend in the front-end development industry.
- React developers are better compensated than other web developing frameworks. According to PayScale, the average salary offered to developers in React.js is $92,341 per year. Compensations increase as you level up in your career — L4 Lead Front End Engineers are paid a high base salary of $115,862 per year.
- It is widely preferred by many companies owing to its simplicity and quick pace and so React developers have a huge demand in the market. Many leading companies like Facebook, PayPal, Instagram, UBER, and Airbnb use React for their web development. Therefore, React developers have a potential future as the technology is used in a wide range of industries.
- Ever since its release in 2013, React has been consistently growing in demand and popularity and Facebook adding many advanced features to the tool is making it more desirable and stronger in the market. ReactJs has completely revamped the front-end handling making it faster and easier by addressing its view issue and providing a UI view and storage layer.
Let us look at the key parameters of React that show its current trend in the market:
|Key Parameters||Figures of React|
|Number of Watchers||6,700|
|Number of Stars||16,400|
|Number of Forks||32,900|
|Number of Contributors||1,533|
- React is also comparatively easier to learn and has a wider community than other libraries like Angular or Vue. The job market for React developers looks very promising.
