If you want to expand your job opportunities as a front-end developer, you should have React on your resume!

Top Reasons to Choose ReactJS

  • Easy to learn and understand
  • Reusability of code
  • Stability of code
  • Quick Rendering
  • SEO friendly and Helpful Development Tool
  • Strong Community support

1. Easy to learn and understand

ReactJS is straightforward and less complicated compared to other JavaScript frameworks. Developers can use standard JavaScript coding for developing web apps on ReactJs. It is also easy to understand and learn the combination of HTML with ReactJS. The syntaxes are more or less similar, and you can also use JSX extension with ease.

2. Reusability of code

It saves lots of time and hassles to write the same code again and again. The best part of it there is no similarity among the components of ReactJS and isolated from each other. Then, changing in one element won’t influence other elements.

3. Stability of code

The best part of ReactJS Development Services is the stability of the code. ReactJS allows the data flow in one direction only that helps to achieve higher stability. In data binding technique if child structure is changed, then it won’t have any effect on the parents’ structure. Changing in object straightforwardly modifies its state. It also removes the risk of alteration in child structure affecting the parent structure, as if data flow downwards.

4. Quick Rendering

Quick rendering is required when heavy applications or dynamic software solutions have been implemented. Unfortunately, many web development services are unable to provide these facilities. The Facebook team assured that ReacJS does not have these issues because they have implemented virtual DOM in order to remove issues in rendering and made the process easier.

Virtual DOM represents traditional document object model virtually that allows you to apply change virtually and execute DOM changes with less effect. This method allows extraordinary user experiences and also improves speed by optimizing the time required for the modification of DOM.

5. SEO friendly and Helpful Development Tool

The prime target for any developer is to develop a website that should be SEO friendly. But the fact is most search engine cannot read the javascript applications. Google has the facility to adjust but other search engines are still struggling to read JavaScript-heavy applications. ReactJS Development Services provides a perfect solution for these issues. It runs on a server and returns a DOM request to the browser and executes as a regular webpage.

This process helps the search engine to crawl your website or mobile app, which is resulted in getting rank in the top of the search engine. ReactJS helps the developer to expose with it’s an extensive toolkit. It has the best debugging and designing tools. Even developers can download a browser extension known as React Developer Tools for both the popular browsers Chrome and Firefox. It is the best extension that allows you to observe reactive components, inspect current state and Profs of different components and find the parents and child components.

6. Strong Community support

One of the best reason for using React Native App Development over the other frontend development is its strong community support. A large community of developers gets support from its open source library and coders from around the world extend their hand to learn the technology in different ways. There are almost more than 1100 contributors on GitHub and an active community of ReactJS on Various forum such as StackOverflow, Stack, Reactiflux Chart, Freenode IRC and others always try to solve your queries. This approach really helps the developer who starts their journey and also boosts their confidence.

This also encourages new developers to make a move toward ReactJS as they know if they face any kind of difficulties while coding any complex structure, then they don’t need to give up, many friends are there to help you out. Some developers and tutors provide tuition to the students by uploading their ReactJS tutorials and write a blog post and in-depth tutorials in order to help the new developers.

At the heart of all React applications are ‘components’. A component is essentially a piece of the user interface(UI). So when building applications with React, we build a bunch of independent, isolated, and reusable components and then compose to build complex user interfaces.

Every React application has at least one component which we refer to as the root component. This component represents the internal application and contains other child components. So every React application is essentially a tree of components.
