How to Hire a React Developer (Step-by-Step)
Posted by InterVenture on August 31, 2023What is React.js?
React.js is a widely used JavaScript library for building user interfaces (UIs). It enables developers to create interactive and dynamic UI components by employing a component-based architecture. React.js efficiently manages the UI updates, automatically refreshing only the necessary parts when data changes occur. This leads to enhanced performance and smoother user experiences. It employs a virtual DOM, a lightweight representation of the actual DOM, which reduces direct manipulation of the real DOM and optimizes rendering speed. React’s popularity has led to a thriving community and an abundance of reusable components and resources. It’s a go-to choice for developing modern web applications that demand responsive and engaging user interfaces.

How to Check React Developer’s Knowledge
What are the main limitations of React.js?
React.js limitations include a learning curve for beginners due to JSX and state concepts, frequent updates requiring adaptation, its primary focus on views requiring additional libraries for full app development, and potential performance overhead in large apps due to the virtual DOM.
What Are the Different Phases of the React Component’s Lifecycle?
The React component lifecycle has three phases: mounting (creation and insertion into DOM), updating (re-rendering due to state/props changes), and unmounting (removal from DOM).
Can you Compare React and Angular?
React focuses on views and uses a virtual DOM for rendering efficiency, while Angular is a comprehensive framework with two-way data binding for state synchronization. React provides more flexibility with tools, while Angular offers an integrated suite of features.
What are Props when it comes to React?
Props (properties) are a way to pass data from a parent component to a child component in React. They enable communication between components by allowing parents to set values that children can access but not modify directly.
What are the differences between a class component and a functional component?
Class components, traditional in React, use JavaScript classes for defining components and state management. Functional components, modernized with hooks, use functions and hooks for simpler, more readable code and improved testability. Functional components are considered a better practice for most scenarios.
Other Points to Consider While Hiring React Developers
Recommendations
Consider candidates with strong recommendations from peers, mentors, or previous employers. Positive endorsements can provide insights into their work ethic, team collaboration, and expertise in React development.
Number of Projects
Evaluate candidates based on the number and complexity of React projects they’ve contributed to. Experience with diverse projects showcases their adaptability, problem-solving skills, and ability to tackle varying challenges.
