1. What is an asynchronous HTTP request, and why is it used?
An asynchronous HTTP request is a type of HTTP request. A client sends it to a server. But the client does not wait for the server's response before continuing with other tasks. Asynchronous HTTP requests are used to improve the responsiveness of web applications. Here are some reasons why they are beneficial:
- Improved performance
- Concurrent processing
- Resource optimization
- Real-time updates
3. How do you interpret a response's HTTP status code when making requests?
- Informational responses (1xx)
- Successful responses (2xx)
- Redirection responses (3xx)
- Client error responses (4xx)
- Server error responses (5xx)
4. Can a Promise-based HTTP client be used for AJAX requests?
- Fetch API
- Browser and Node.js support
- Cross-platform compatibility
- Intercepting requests and responses
- Built-in CSRF protection
- Canceling requests
- Rich request and response handling
