If you’re looking to hire ReactJS developers, consider the following questions to ask during an interview with ReactJS Developers:
Basic React.js Interview Questions
When looking to hire dedicated ReactJS developers, conducting thorough interviews is essential to ensure that candidates possess the requisite skills. To streamline your hiring process, here are some fundamental React.js interview questions designed to assess a candidate’s knowledge, problem-solving abilities, and proficiency in this dynamic JavaScript library:
Ques: What is React JS? Explain some of its features.
Ans: React JS is a JavaScript library developed by Facebook, and it is primarily used to build user interfaces, particularly for single-page applications. Its key features include:
- Declarative: React makes it easy to create interactive UIs predictably and efficiently.
- Component-Based: In React, the UI is divided into various independent, reusable pieces called components.
- Learn Once, Write Anywhere: React can be used with other libraries or frameworks like AngularJS.
- Virtual DOM: React updates efficiently and renders only necessary components when data changes, providing a highly performant user interface.
Ques: What is JSX? Why can a browser not read JSX?
Ans: JSX is a syntax extension for JavaScript, which is widely used with React to describe the UI and enhance the appearance of React components. JSX gets transformed into JavaScript function calls called “React elements” during the build process. Using JSX improves code readability and maintainability and enables the use of React’s component-based architecture.
Web browsers cannot directly read JSX files as it is not regular JavaScript objects, and there are no implementations of the browser engines to read and understand them. However, if you want a web browser to read a JSX file, then you can convert it into a native JavaScript object using Babel.
Ques: What is a Virtual DOM? Explain its working in brief.
Ans: Virtual DOM is a programming concept where DOM stands for Document Object Model and represents the entire UI of the application. Virtual DOM is a representation of a tree where each element acts as a node in a tree. So, whenever the state of any element changes, it re-renders the entire virtual representation to find the difference (diffing) with the actual DOM, and then it updates the real DOM efficiently by only changing the parts that have been altered. The diagram below shows how virtual DOM works:

Ques: What are the new features for function in ES6?
Ans: ES6, also known as ECMAScript 2015, brought significant changes to JavaScript, including new features for functions:
- Arrow functions: These provide a new way of writing concise functions using the ‘=>’ syntax.
- Default parameters: These allow function parameters to be initialized with default values if no value or undefined is passed.
- Rest parameters: These allow a function to accept an indefinite number of parameters as an array.
- Spread operator: This allows an iterable to be expanded in places where zero or more arguments or elements are expected.
- Enhanced object literals: These allow setting the prototype at construction, shorthand for ‘foo: foo’ assignments, defining methods, and making super calls.
ReactJS Interview Questions on Components
When you decide to hire dedicated ReactJS developers, assessing their proficiency in working with components is crucial. Asking the right questions during the interview process not only evaluates their technical expertise but also provides insights into their problem-solving skills. Explore these ReactJS interview questions focused on components:
Ques: What are the components in React?
Ans: Components in React are the building blocks of any React application, and a single app usually consists of multiple components. These components are independent, reusable pieces that together make up your application. There are two types of components in React – Functional components and Class components.
Functional Components: Functional components derive data from props (known as properties) and return React elements. These are JavaScript functions that start with the “function” keyword, as shown below:
Class Components: Class components are created using ES6’s class syntax and include features like local state and lifecycle methods. They have a separate render method to return JSX. Class components start with the “class” keyword, as shown below:
Ques: What is a state in React? How do you implement it?
Ans: In React, a state is an object that holds property values specifically for a component. It’s created in the component’s constructor and can store information that might change while the component is being used.
The ‘setState’ method is used to update the state, and whenever it changes, the component will re-render.
Ques: How do you style React components?
Ans: There are several ways to style React components:
- Inline styling, which involves writing the CSS style directly within the React element
- CSS stylesheets, which involve creating a separate CSS file and importing it into your React file
- CSS modules, where a unique class name is generated for each CSS module to avoid clashes in the global scope
Additionally, libraries such as styled-components or emotion allow for CSS-in-JS solutions, where styling is written in JavaScript files.
Miscellaneous React.js Interview Questions
To hire dedicated ReactJS developers, evaluating their technical proficiency is paramount. To assist recruiters and hiring managers in the selection process, we’ve compiled a set of miscellaneous React.js interview questions as follows:
Ques: What issues are addressed by the CSS module?
Ans: The CSS Modules are a way to tackle problems related to the global scope of CSS. They help to avoid class name collisions by generating unique class names for each CSS module. They also promote modularity and reusability by restricting styles to the components where they are defined.
Ques: Explain the concept of the High Order Components (HOC) in React.
Ans: Higher-order components (HOCs) are a popular design pattern in React. They are functions that take a component as input and return an enhanced component. HOCs enable code reusability by adding additional functionality to the wrapped component. They are useful for implementing features like authentication, data fetching, and code abstraction.
