Essential Interview Questions for Frontend Developer
What are the key differences between functional and class components in React?
Functional components are simpler and primarily used for presentation. They are functions that return JSX. Class components, on the other hand, are more complex, stateful, and offer lifecycle methods. React Hooks have enabled functional components to manage state and side effects, reducing the need for class components.How do you handle state management in a large scale React application?
For managing state in large React applications, I prefer using Redux or Zustand. These libraries provide a predictable state container, making it easier to manage complex data flows and application states. Context API can be used for smaller applications, but Redux or Zustand offer better scalability and maintainability for larger projects within Switzerland.Explain the concept of 'virtual DOM' and its advantages.
The virtual DOM is a lightweight in memory representation of the actual DOM. When the state of a component changes, React updates the virtual DOM first, then compares it to the previous version to identify the minimal set of changes needed to update the actual DOM. This process, known as 'reconciliation,' significantly improves performance by reducing direct DOM manipulations.Describe your experience with different testing frameworks for frontend applications.
I have experience with Jest and Cypress for testing frontend applications. Jest is excellent for unit testing React components, while Cypress is ideal for end to end testing, ensuring the application behaves correctly from the user's perspective. I also have experience with React Testing Library for integration tests. Using these tools helps ensure code quality.How do you optimize a website's performance as a frontend developer?
Website performance optimization involves several strategies, including code splitting, lazy loading images, and using efficient CSS selectors. I also focus on minimizing HTTP requests, caching assets, and optimizing images. Profiling tools help identify performance bottlenecks. I always ensure that the application is responsive and provides a smooth user experience.Can you explain the importance of web accessibility and how you implement it in your projects?
Web accessibility is crucial to ensure that websites are usable by people with disabilities. I implement accessibility by using semantic HTML, providing alternative text for images, ensuring sufficient color contrast, and making the application keyboard navigable. I also use ARIA attributes to enhance accessibility and regularly test with screen readers to ensure compliance with accessibility standards.Recommended Job Offers for You
