Hello developers’ community! For several years now, statistics on the popularity of various IT technologies have been published annually in the public domain. ReactJS has consistently taken the lead in the web development category. More and more vacancies appear on the labor market, and courses offer to quickly master a new profession of ReactJS developer. So that you do not get lost in Google search results, I wrote this article which is called ‘What Are The Duties And Responsibilities Of ReactJS Developer’. The article is intended both for novice React developers who want to find out what tasks await them in their future work, as well as for employers who are interested in the range of professional tasks of such a specialist. Let’s start from the beginning!

ReactJS development refers to web development, namely the creation of the user interface (front-end development). In this very popular IT direction, programming and layout are combined, without which no website or application is created. The front-end developer ensures the interactivity of the page and designs it as the designer intended. The JavaScript programming language and, accordingly, the CSS and HTML layout tools help him in this. React is a JavaScript library, a web interface development tool. It allows to create the structure of a software project, has certain templates and the ability to change them. Such a tool makes the task of ReactJS developers easier, and helps to make the development process easier and faster. ReactJS has certain functionality and requires knowledge to use it. Large companies and social networks use the services of developers with React knowledge, because they can complete a large amount of tasks and find modern solutions for their business. High performance of products written in React is achieved using the virtual DOM, usability is guaranteed by isomorphism, and code reuse in different projects is a huge advantage in the process of creating a project. To determine what responsibilities a React developer has, you need to consider the functions and nuances of this framework.

Key features of ReactJS:

using composition of components written by different developers who work in one development team;
availability for a wide range of developers with different levels of experience and skills;
stability of the API – the programming interface for creating new applications;
compatibility with other codes that not written in React;
comfortable development process;
ability to find the source of the error in the code base;
visualization of the object model of an HTML document – DOM;
using React to build mobile apps – React Native.

It is worth noting that ReactJS developer’s duties and responsibilities are different by level. Also, the requirements for developers depend on the company. Therefore, the best option is to go through as many interviews as possible. Often, even this process itself significantly improves the beginner, because he understands what he is missing and can and can learn new information before the next interview. Before interviews, you should improve your skills in the technologies listed above and create a portfolio. The importance of the portfolio can hardly be overestimated – even if the works in it will not be related to the topic of the work vector of the selected company, the diligence and desire to develop will still be appreciated. It is often beneficial for the employer to take on the team ‘charged’ newcomers who are ready to develop and try to move towards the goal on their own. Do not forget about soft skills – development takes place in a team, which means that the improved skills of interaction, distribution of tasks and working hours, and conflict resolution will be as relevant as possible. An unquenchable interest in professional development, self-organization, and the ability to quickly absorb new information are also very important qualities. Another tool that such a ReactJS specialist needs to master is HTML. It is a hypertext markup language for browsers that read this language, interpret it and display it as a generated document. This is necessary to structure it and display it correctly for everyone on the Internet. The associated language, CSS, aims to describe the appearance of a document written in HTML. These are cascading style sheets that infuse the markup with design elements. Therefore, HTML and CSS are used together for site layout.

As it was already written above, the responsibilities of the developer depend on his level. Let’s start with Junior ReactJS Developer. Usually you can become a Junior after completing IT courses in a few months. Such developers know the base and may even have worked as layout designers or JavaScript developers. They already have some kind of portfolio with their completed ReactJS projects. It is vital for a junior to find an internship or a job where he will be accompanied by a guide – in this case, he will pump faster and be able to move to a next level. At this stage, he ought to constantly develop his knowledge and try to learn something new in the selected technologies as much as possible.

The next level is Middle ReactJS Developer. A middle-level specialist is a person who is ready to move in right direction and complete tasks properly. That is, he already sees the needs of the customer and can solve them. Development of web applications and other products becomes a task for him, starting with understanding the goals of the client. Often it is at this moment that there is an urgent need for knowledge of the English language, as a specialist begins to be entrusted with presentations of the work done, but this greatly depends on the company – some may not work with a foreign market, while others may entrust presentations only to seniors.

The Senior ReactJS Developer has the most duties and responsibilities. In addition to the ability to create a well-built architecture, he also needs soft skills. Team building, mentoring and management skills will be especially relevant. Often it is an experienced programmer, who becomes a teacher for talented beginners. Also, Senior ReactJS developers with more than 3 years of experience must understand how the browser works at the GC and rendering level, think over the general design of the company, the uniform style of external and internal projects, and understand SEO optimization.

Conclusion

As you understood after reading the article ‘What Are The Duties And Responsibilities Of ReactJS Developer’, ReactJS has a wide range of possibilities in web development and such a specialist must use all these possibilities in the process of developing an IT product. But do not forget that developers are divided into levels and the requirements for them also depend on the companies. Hope this information was useful and interesting for you. Good luck!
