Author: Nayantika Srivastava

With the increasing popularity of ReactJS, there is a growing demand for developers with ReactJS skills. However, it is not enough to simply hire a ReactJS developer – it is important to ensure that the developer has the right skills for the job. Regardless, with such high demand comes the challenge of finding developers with the right skillset. To find the best ReactJS developers, it's important to screen for their skills. This blog will help you understand the important react js developer skills that you need to screen while hiring React developers for your organization.

Top 5 Technical Skills to Screen While Hiring a React JS Developer

When screening potential React developers, it’s important to assess their react js developer skill set in these areas. Here are five technical skills you should look for:

  • Strong Understanding of JavaScript

React is a JavaScript library, so developers need to have a strong understanding of JS syntax, conditions, loops, functions, and objects. They should also be familiar with ES6/7 syntax and features.

  • Familiarity with JSX

JSX is an XML-like syntax used by React for templating. It’s not necessary to use JSX when working with React, but it’s recommended because it makes code more readable and helps avoid cross-site scripting (XSS) attacks. React developer skills should include the ability to write JSX code and understand how to use Babel to convert it into regular JavaScript.

  • Understanding of State

In React, state refers to an object that holds information that may change during the lifetime of a component. Developers need to understand when and how to use state in a React component. They should also know how to initialize state and how to update it when necessary.

  • Proficiency in Using Development Tools

React developers need to be familiar with development tools such as Babel and webpack. Babel is used to convert JSX into regular JavaScript, while webpack is used for module bundling ( compiling multiple files into one ). Familiarity with other build tools such as Gulp or Grunt is also a plus.

  • Understanding of Testing Frameworks

Because bugs are inevitable in any software application, it’s important that React developers know how to use testing frameworks such as Jest or Enzyme. This skills for react developers allows them to write unit tests for their components and catch any bugs before the application goes live.

Technical Terms Hiring Managers Should Know While Screening a React JS Developer

If you are a hiring manager who is looking to screen skills required for react js developer, then understanding some of the technical terms is essential. By understanding these key concepts, you can better gauge a candidate's skill level and fit for the role. With this knowledge, you can make more informed decisions when it comes to hiring React JS developers.

Below are 8 React technical terms that every hiring manager should know:

  • JSX

JSX is a syntax extension to JavaScript which creates XML-like tree structures within the code. It is used by React to create reusable UI components.

  • Virtual DOM

The virtual DOM is a lightweight JavaScript object that represents the real DOM. It acts as a layer between the UI and the actual DOM. Any changes made to the virtual DOM will be reflected on the real DOM without having to update the entire page.

  • Component

In React, a component is a self-contained piece of code that can be reused throughout an application. There are two types of components: functional and class-based components.

  • Props

Props stands for properties and are used to pass data from one component to another. props are immutable and cannot be changed by the child component.

  • State

State is used to manage data that will be changed over time. Unlike props, state can be changed by the component itself.

  • Lifecycle Methods

Lifecycle methods are a series of methods that are invoked at different points in a component's life cycle. They allow developers to run code at specific points in time which helps with things such as managing state or performing API calls.

  • Higher-order Components (HOC)

Higher-order components are functions that take a component as an argument and return a new enhanced component. HOCs are used for adding functionality to existing components such as adding state or life cycle methods without having to rewrite existing code.

  • Render Props

It is a technique for sharing code between components using props instead of inheritance. This react front end developer skills allow developers to use a single component multiple times with different rendering logic each time it's used.

Conclusion
