What is React?

React is also known as ReactJS. It is an open-source JS or JavaScript library utilized for developing interactive UIs (User Interfaces). With respect to web applications and websites, User Interfaces are regarded as collections of on-screen menus, buttons, search bars, or any other component a user will be interacting with for using an app or website. ReactJS was launched by Facebook in 2013. It is utilized as a foundation for mobile apps or single-page web pages with the help of React Native.

React developers are capable of building User Interfaces in the form of smaller pieces -referred to as components. A component is a mixture of JavaScript and HTML that is capable of capturing all the important logic required for displaying a smaller section of some large UI. Each of the given components can be built up into complex parts of the app.

Top Skills for the React Developers

#HTML/CSS

React JS is a type of front-end development framework. Therefore, it is important for a React JS developer to have in-depth knowledge of the same. The app interface is one of the most interesting aspects that attracts users while luring them into engaging with the app. Irrespective of the type of application you will be developing, every ReactJS programmer should have extensive knowledge of CSS and HTML concepts.

A front-end developer should have relevant knowledge about CSS and HTML while having the ability to work with user interfaces and develop great applications for enterprises across multiple industry verticals. For instance, the ability to work on HTML tags and CSS selectors are must-haves for a developer.

#JSX

Just like HTML, JSX is regarded as the extension of the ReactJS environment. It is another interesting aspect of ReactJS development. While working with ReactJS, a developer will not be getting involved with HTML significantly. On the other hand, a majority of interaction takes place with JSX. It is regarded as the syntax extension of ReactJS.

The fact that makes JSX an important part of ReactJS development is that it enables developers to develop applications with the help of API.

#Git

Every ReactJS developer should be aware of the Git toolkit. It offers them ample flexibility to consider adding or updating projects on multiple coding forums -like Gitlab, Github, and the BitBucket. It is important for the developer to be aware of these platforms to ensure the following:

• Keep a track of the modifications with a proper comment

• Management of merge conflicts

• Merging and branching of strategies

#JavaScript Fundamentals and ES6

Another important skill that your professional ReactJS developer should possess is hands-on experience in JavaScript Fundamentals along with ES6. Only when the developer will have profound knowledge of both the aspects, he or she will be capable of making the most out of the framework. Some of the core ES6 skills are:

• Array methods

• Variables and scoping

#Redux

It is the state management library of ReactJS. Redux is another core skill set or feature that a developer should possess. Redux is mostly regarded as the principle of functional programming and immutablity.

#Node and NPM

Eventually, the developer should possess the knowledge of Node. A developer having proper knowledge of Nodes is capable of highlighting and understanding the development requirements of the clients. There are particular packages in the node that can be extended to the ReactJS library. Therefore, the knowledge of Node and NPM helps with the overall development process.

#Knowledge of Tools and Technologies

Some essential tools and technologies at which a ReactJS developer should be adept at are:

• Enzyme -for facilitating the testing of React apps

• Jest -Built-in tool for testing JavaScript code

• Redux -for managing the management state

• Bitrise -for improved automation

• Sentry -for ensuring real-time monitoring and fixing crashes

• Hockeyapp -for managing testers, crash reporting, and beta distribution

• ESLint -for validating the code as per the JavaScript patterns

#Proficiency in ECMA Script and JavaScript

In addition to the essential technical skills, it is important to hire dedicated ReactJS developers having strong command over all important operations, features, and syntax. Moreover, they should also possess a proper understanding of aspects like DOM manipulation, hosting, functions, JS scopes, and prototypal inheritance.

Moreover, the ECMA Script also plays a crucial role in the development of ReactJS applications. The ECMA Script is typically responsible for writing single-line code or simplifying JavaScript code with the help of Deconstructing feature. Therefore, ReactJS developers who are proficient in ECMA Script and JavaScript are highly experienced.

#Experts in Equivalent Technologies

It is not sufficient to be an expert only in a single framework or technology. A ReactJS developer should also be an expert and competent in working with a number of technologies that remain compatible with React.

For beginners, a backend framework or platform is required for hosting a feature-rich React.js application. Therefore, in-depth knowledge of these back-end technologies is a must for a professional ReactJS developer. Moreover, the potential ReactJS developer should also possess relevant expertise in MERN (MongoDB, ExpressJS, ReactJS, and NodeJS). This is because the MERN Stack is highly preferred for the development of full-stack JS apps in the modern era.

Therefore, it can be said that the ReactJS developer you hire should have ample knowledge and experience in relevant technologies for building a reliable and compatible React.js application.

Conclusion

There are several aspects you should consider while hiring a professional React.js developer for your project. Ensure that you look deeply into these factors to ensure optimized results for your development project. Hire React developers from a reliable and reputed ReactJS development company.
