Frontend Intern Interview Questions & Answers – Jupiter
Technical Interview Questions
1. What is React, and why do we use it?
Answer:
React is a JavaScript library used to build user interfaces (UI), especially for web apps. It helps developers create reusable components and makes web pages faster and more interactive. Jupiter uses React because it allows building modern apps that look and work well on different devices.
2. What is a component in React?
Answer:
A component is like a building block in React. It is a small, reusable piece of code that returns HTML (JSX). You can use components to build sections like a button, a header, or a form. This makes your code organized and easy to manage.
3. What is the difference between a class component and a functional component?
Answer:
-
Class Component uses ES6 classes and can have state and lifecycle methods.
-
Functional Component is a simpler way to write components using functions. Since React 16.8, functional components can use Hooks to have state and other features.
Example:
// Functional Component
function Welcome() {
return <h1>Hello</h1>;
}
4. What is JSX?
Answer:
JSX stands for JavaScript XML. It allows us to write HTML inside JavaScript. It looks like HTML but it’s actually JavaScript. React uses JSX to create UI in a readable way.
Example:
const element = <h1>Hello, world!</h1>;
5. What are props and state in React?
Answer:
-
Props (short for properties) are used to pass data from one component to another.
-
State is used to store data inside a component that can change over time.
6. What is the use of useState and useEffect in React?
Answer:
-
useState is a Hook that lets you add state to a functional component.
-
useEffect is a Hook that lets you run side effects (like API calls, timers) in functional components.
7. What is the Virtual DOM?
Answer:
The Virtual DOM is a copy of the real DOM (Document Object Model). React uses it to see what changes are needed and then updates only the changed parts. This makes React apps fast and efficient.
8. How do you handle API calls in React?
Answer:
You can use the fetch() method or libraries like Axios to call APIs. These calls are usually made inside the useEffect hook after the component loads.
Example:
useEffect(() => {
fetch('https://api.example.com/data')
.then(res => res.json())
.then(data => setData(data));
}, []);
9. What is Git and why is it used?
Answer:
Git is a version control system. It helps developers track changes, work in teams, and roll back to previous versions if needed. It’s very useful when working on large projects with multiple developers.
10. Have you worked with any testing tools like Jest or React Testing Library?
Answer:
(If yes):
Yes, I have used Jest and React Testing Library to write unit tests for components. It helps make sure that the component works as expected.
(If no):
I’ve read about them and am learning how to write tests. I understand their importance in ensuring app quality.
