Understanding Synchronous and Asynchronous Requests in Ajax

When working with Ajax, it's important to understand the difference between synchronous and asynchronous requests.

Synchronous Requests:

Synchronous requests block the browser until the request is completed, meaning the user cannot interact with the page during this time.

Use synchronous requests when the order of operations is critical, such as when making multiple dependent requests that require the previous one to finish before the next can start.

Asynchronous Requests:

Asynchronous requests do not block the browser and allow the user to continue interacting with the page while the request is being processed.

Use asynchronous requests when you want to improve the user experience by allowing for non-blocking operations, such as fetching data in the background without interrupting the user's flow.

It's important to choose the right type of request based on the specific requirements of your application to ensure optimal performance and user experience.
