Top 7 React JS Developer Technical Skills When Hiring

Here are the seven React JS developer skill set that every hiring manager must actively seek:

1. HTML and CSS

skills for react developer

If you are looking to fill the vacancy for a React front-end developer, HTML and CSS are core skills that will come to play. The candidate’s knowledge of these client-side technologies and important react developer tools sheds light on their ability to create and work with value-loaded, visually-aesthetic, and highly intuitive user interfaces (UIs). Given that UIs now play a crucial role in determining the perceived value and quality of an application, the React JS developer skill set can indirectly affect the same.

At a high level, the candidate should at least be in a position to work with and write HTML tags and CSS selectors while also having an understanding of the box model. Basic React front-end developer skills like performing CSS reset, implementing responsive web principles, and reverting to border-box are also essential qualifications.

2. Fundamentals of JavaScript

skills required for react js developer

JavaScript is one of the primary skills required for ReactJS developers. As such, you will have to test their knowledge of JavaScript concepts surrounding code structure, variables, data types, operators, functions, loops, switch statements, objects, primitives, boolean, arrays, and more. It is crucial to give these principles their due importance as these fundamentals of JavaScript would also be applicable while coding in ReactJS web development. So, if their foundational knowledge is spot-on, their React JS developer skills would follow suit.

3. JavaScript ES6

skills required for react js developer

In addition to the fundamentals of JavaScript, a React developer’s skills must also be complemented with a solid understanding of ES6 (ECMAScript 2015 or ECMAScript 6). This newer version of JavaScript enables the developer to build and maintain web apps as per your requirements.

The most sought-after React JS Developer skills for ES6 include scoping variables, array methods, arrow functions, DOM manipulation, event handling, high-order functions, call-back functions, ‘this’ keyword, and so on. On close observation, it is evident that ES6 is somewhat of an advancement of the fundamentals of JavaScript discussed previously, and thus considered a key question asked during react developer interview. Hence, we repeat that these React JS developer skills may be different but should be treated as complementary.

4. JSX (JavaScript XML)

react js developer skill set

Since we’re already on the topic of JavaScript and its importance as a skill for React developers, JSX also deserves a special mention. JSX is a syntax extension to JavaScript that allows coding in an ergonomic fashion. ReactJS developers having JSX skills can effortlessly code and incorporate HTML/XML elements in React. Equipped with this knowledge, React developers can also build applications that utilize React APIs – an otherwise tedious task. In addition to expediting and streamlining app development, JSX is also used to enhance app scalability – without complicating the code.

Do note that Babel, a JavaScript parser can convert HTML syntax into basic JavaScript files. As such, a ReactJS developer with Babel skills could be a fitting substitute for JSX depending on your requirement.

5. Git

react developer skills

ReactJS developers who have a grasp of Git are excellent at version control, code storage, and maintenance. Such ReactJS developer skills enable them to store the project on centralized version control systems like GitHub, GitLab, and BitBucket. Developers can make necessary modifications to the code using commands like push, pull, comment, add, etc. Git maintains a record of these changes and allows the developers to merge or isolate branches to test code performance under varying conditions.

As a result, the developer can launch features or retract them one by one without affecting the source code or other modules. From this very definition and role, it is clear that the React JS developers’ Git skills can be instrumental in maintaining code flexibility without critical data or functionality losses.

6. Node + npm

skills for react developer

Node may be a necessity if you are looking specifically for a ReactJS full stack developer with requisite skills. While React could cater to front-end development, Node would take care of the back-end development. The MERN (MongoDB, Express, React, Node) stack is a perfect example of such a full-stack environment. One must also consider the fact that developers can run React codes directly in the Node environment, and vice versa, which further enhances their interoperability.

Additionally, with React featuring on the server-side and client-side script, having knowledge of Node can be particularly useful. And since you already seek such React JS developer skills as a prerequisite, also make sure that they possess a detailed understanding of the NPM (Node Packet Manager) registry. This registry can help developers and react js development  services companies unlock more value within the React library and update app packages.

7. Redux

react js developer skills

Asynchronous state updates are one of the weakest links of React development. And this is why the ability to understand and work with Redux becomes one of the most crucial ReactJS developer skills

Redux is a built-in state that allows a developer to control and preserve the React library. Developers use it for state management through the lens of scalability. By imbibing the principles of functional programming and immutability, Redux helps the developer produce apps that behave in a consistent manner, are easy to test, and operate similarly in different environments. 

Top 3 React JS Developer Soft Skills to Screen When Hiring

Now that we’ve wrapped up the technical skills required for screening ReactJS developers, let’s take a look at some soft skills that need to be evaluated:

1. Excellent Communication

The app development process calls for constant communication – whether it is within the team or externally with the stakeholders. In such cases, the ReactJS developer would often find themselves conducting such interactions with a bunch of people having varied technical and non-technical exposure. As such, the developer should have excellent communication skills to engage everyone involved in the development process, understand project requirements, convey the said requirements to team members, share progress updates, etc.

2. Problem-Solving Approach

The developer’s logical thinking, reasoning, and understanding, all contribute to their problem-solving approach. In fact, how they switch from identifying the problem to postulating a solution determines the project’s success – each of these stages relies on the problem-solving approach and capabilities of the individual.

Similarly, this skill also comes under scrutiny when inadvertent mistakes might pop up during the development process and the developer will have to address such issues while devising and discovering appropriate resolutions. As such, you need someone who is unafraid to think out of the box and who is open to making mistakes and learning from them.

3. Ability to Work in a Team

ReactJS developers are not lone wolves running in the wild. Even the most self-sufficient individuals having absolute React full-stack developer skills would have to work with other team members such as the product owner, tester, designer, etc.

As such, they need to have a persona that allows them to gel with others and contribute to the team. After all, all their technical skills and knowledge go down the drain if they are unable to work within a team.

Technical or “hard” skills are task-specific abilities required to complete a job. These talents can be cultivated through education, seminars, training, and certifications.

However, soft skills are more concerned with a person’s capacity for interpersonal interaction. They are difficult to measure or quantify by nature. And that’s why you need a talent management grid for an efficient assessment of your preferred candidate. Soft skills allow us to assess a candidate’s interpersonal abilities and compatibility with the company’s culture. The following are some of the most crucial soft skills for a React developer:

  • Effective communication abilities
  • Teamwork
  • Creativity
  • Being receptive to feedback
