Can you explain how fetching data affects the performance of a web application?
Fetching data can significantly impact performance, especially if the requests are slow or if there are too many of them. It can lead to longer load times and a poor user experience.
What are some ways to optimize data fetching?
You can optimize data fetching by using techniques like caching, lazy loading, and batching requests to reduce the number of calls made.
How does caching improve performance?
Caching stores previously fetched data, allowing the application to retrieve it quickly without making a new request, which speeds up load times.
Are there any tools to help with optimizing fetching?
Yes, tools like Postman for testing APIs, and libraries like Axios or Fetch API for managing requests can help optimize fetching.
