10 reasons why developers need ReactJS

 

React is a fast-growing JavaScript library developed and popularized by Facebook and Instagram. The main purpose of React is to build user interfaces. If you are picking the best library for your project, or you are a novice in web development and struggling to pick a starting point then this article is for you. Without further ado, here are 10 reasons why developers need ReactJS:

1. Components in web development

React.js follows the polymorphism principle of the object-oriented programming. Inheriting this feature from another JS framework called Polymer JS. But React.js takes to a whole other level. Allowing you to to create components, that can be reused later, combined, or nested into another project.

2. React.js is efficient

One of the main features of React.js is that it creates its own virtual Document Object Model to store the components. Virtual DOM has the same properties as the real DOM, but it can’t directly change what is on screen. Why is it a good thing? Thanks to this approach React.js analyzes the changes that have to be made inside the virtual DOM and updates it in advance. Thus improving the performance and provides a higher level of flexibility for the developers.

3. React.js boosts SEO

Since recent updates, Google is able to execute and index JavaScript during his “crawls”. Interestingly, some tests report that DOM content is preferable than plain HTML. Only a handful of tests have shown this result, though. But, clearly, DOM content is recognized by Google. A bonus point is that React.js can run on the server, so the virtual DOM will be rendered and pushed to the browser as an ordinary web page. Boosting the SEO performance of your page along the way.

4. Flexible code that is easy to maintain and design

Many say that React.js platform is out-of-the-box ready. That’s because of the many features that help developers do their work. For example, React.js platform allows developers to restore a code that was written a week or even a month earlier without browsing the GitHub. Trust me, this is a huge timesaver. Furthermore, the React.js can provide pixel-perfect designs in a moment, all thanks to small and self-contained elements. There are elements for almost everything, for a button, field, background, you name it. Thanks to this structure, React.js developers are more open to changes.

5. React provides an easy way to deal with a lot of data

Vanilla JS can get a little bit too complicated when you are trying to manage a large amount of information. Sometimes, you have to create so many instances of information, that it feels like you are littering.

That’s why React has a feature that is called “state”. It is a place where the data comes from. Using it developers can minimize the number of stateful components. All that is achieved with simple and intuitive code.

6. React doesn’t actually do a lot

Don’t be misled. It is actually a good thing. Developers hate when the software does something without their knowledge. Sometimes, they check their code a dozen times and then find out that they didn’t do anything wrong it’s just some built-in feature messing with them. That’s when the keyboards are broken and headphones fly into the monitor.

React is the V in an MV. I mean, that it is a tool that can help software engineers to build a view layer without gathering or imposing any data from other layers.

7. React applies functional programming ideas to the view layer

Most of the modern applications are made according to the object-oriented programming model. That is why they have so many moving parts, with different variables, values, etc. While bringing a lot of positive features to the table it leads to different edge cases and problems.

On the other hand, React.js components are pure functional components. This implies that one input leads to the same output. React.js is independent of the outside values.

8. React has a CLI (Command-line Interface)

React Developers love the console. That’s a fact. However, for a long period of time React.js didn’t have a CLI(command-line interface) and it provides a possibility to build a new project from scratch. It did cause a lot of confusion and struggle for people trying to learn React.Js. That’s why in July of the last year Facebook upgraded React by adding a CLI. Now it is a lot easier to get started with React.js.

9. React gives you the full power of JavaScript

React.JS is really different from the other JavaScript frameworks. And not like a run-of-the-mill teenager, really different. There is a thing was that done in an opposite way to other frameworks – the templating of React.js is done with something called JSX. This concept allows you to pull full language of JS to HTML. Other JavaScript frameworks do the opposite, they take the template of HTML and bring JS to its level.

10. Start small with React

React.js is really easy to implement. If you decide to try it out, there is no need to rebuild all your interface using React.js. You can focus on one small area or element, and try out new technology there. Without any risk of breaking your whole project. Start small, and if you like it, you can scale up and sooner or later rewrite all of the UI with React. Because it is worth it.

Conclusion

Well, that’s it! There are plenty more reasons why developers need ReactJS. But the name of this article implies that I write only 10. If you are interested in React.JS and want to give a try then check out the tutorials first. If you are already familiar with React then check out this benchmarks vs Nodejs, I am sure you will find a few new things there.
