ReactJS is one of the best JavaScript libraries with a powerful community of experts. It is mainly used for front-end development. There are many different roles and responsibilities for ReactJS developers for offering the best services to clients.

After seeing the popularity of this technology and the demand for ReactJS developers in the web development market, every software engineer wants to become a ReactJS expert. For this, they must have some basic knowledge about the field and its future. Therefore, in this blog, we will learn more about how ReactJS developers work, the essential skills they must have, the future scope for React web app developers, and their salary structure.

1. ReactJs Developer: An Overview

In any web development company, a ReactJS developer is responsible for creating, designing, and implementing user interface components for web and mobile apps that are based on JavaScript. For this, the developers use open-source Javascript library infrastructure. These React developers are an integral part of the entire web app development process starting from conception to the testing. They follow ReactJS workflows like Flux to complete tasks like building user interfaces or single-page applications.

Besides this, these front-end developers create modern-day UI components to improvise application performance. They take advantage of their knowledge about HTML, JavaScript, and CSS to work closely with other software development team members like web designers, web app testers, and project managers who are working to create an effective and robust web application. 

In addition to this, ReactJS developers have been enabling the business owner to focus on his core business areas and handle the entire IT-related activities without bothering anyone. This is something that has helped in enhancing client satisfaction.

2. Essential Skills for React Web Developers

Skills For React Web Developers

Some of the major skills that every React web app developer must have are –

2.1 HTML + CSS

HyperText Markup Language also known as HTML is one of the most popular standard markup languages for web app designers to create and structure paragraphs, sections, and links with the use of various attributes, tags, and elements. It is a language that enables web developers to create dynamic functionalities by merging with technologies such as scripting languages like JavaScript and CSS.

Cascading Style Sheets, also known as CSS is a popular style sheet language that enables designers to create great-looking web pages. Basically, it is a language that is used to describe the presentation of a page written in a markup language like XML or HTML.

Every front-end developer is familiar with these two technologies. And both HTML and CSS have the ability to offer amazing outcomes. Developers use both of them together to create user interfaces for the web application for every business organization. This is why every React developer at a high level must have the following abilities:

  • Programmers must be able to work with HTML tags and write semantically.
  • React developers should be capable enough to work with CSS selectors and write them.
  • The React experts must have a proper understanding of the box model and how to reset it to the border box.
  • The web app developers must be able to implement a CSS reset.
  • They must have knowledge about flexbox.
  • Developers must be able to implement responsive web principles with the help of media queries.

2.2 JSX

When it comes to React, developers don’t actually use HTML properly. They work with a syntax extension. It is something that is truly one of the best parts of the ecosystem of the React library. It is known as JSX (JavaScript XML). JSX has a similar look to HTML and this is why many beginners think that it is HTML-flavored JavaScript but it’s not. Besides, JSX is a technology that can be learned easily if someone has basic knowledge of both HTML and CSS.

In the world of programming, JSX is known as an abstraction that is present on top of React.createElement() API. One of the main reasons behind it being essential for the React library and why React developers chose it over any other technology is that the API in JSX would be cumbersome to use.

Apart from this developers can use React.createElement() function to create an entire application, but that web app won’t be as efficient and effective as required and the reason behind this is, that there would be no proper usage of HTML. Because of this at first, it might feel that the developer has taken a step backward by adding Markup into template logic, but eventually, it will give a perfect application.

2.3 Redux

Another technology that every React developer must be aware of is Redux. React comes with built-in state management and many developers have worked really hard to discover the asynchronicity of state updates & ways React handles them. This is the only reason why Redux was born. It came into the React ecosystem to offer scalability. Basically, Redux is known as a popular state management library. It is not a framework for creating applications but is an opinionated way to work with important data.

The main principles behind Redux are immutability and functional programming. But this tech stack doesn’t offer a one-size-fits-all solution. Any developer who wants to master Redux must have a fundamental knowledge of React programming.

After going through the three most popular technical skills that every React developer must have, let’s go through some of the soft skills which are also required –

  • Any web app developer must have accountability and creativity.
  • They must have the competence to translate business requirements into technical needs by applying business logic.
  • Skills like good time management, communication, project management, and interpersonal skills are required.
  • Every developer must be an open-minded team player and should be willing to accept all types of feedback and offer suggestions
  • The React developer must have the willingness to learn modern processes and tools.
  • They should have the capability to write crisp and clear code as per the standard practice and guidelines.
  • Good troubleshooting and problem-solving skills are a must.

3. ReactJS Developer – Roles And Responsibilities

In comparison with other competitors, ReactJS developers get highly paid and are very much in demand. This is why Facebook, the giant behind React, and its entire community are trying hard to continue enhancing the speed and effectiveness of ReactJS. 

This clearly proves that no matter how many new technologies come into the market, this JavaScript library will keep fighting the competition and stand out as a winner. In addition to this, Facebook always launches new updates which keep this technology latest.

Besides this, React comes with a newer fragment syntax to JSX that requires no keys. It also enables the web app developers to take advantage of the new and improvised error handling approach which was difficult at one point. 

React community also enhanced server-side rendering for the developers. The way React is growing, it is very much clear that the demand for ReactJS developers will go higher with time.
