What is the difference between ajax and axios?

Ajax is a technology based on native JavaScript that allows for asynchronous communication with servers without refreshing the entire page. It uses the XMLHttpRequest object to send requests and handle responses.

Axios is a Promise-based HTTP client used for sending HTTP requests in both browsers and Node.js. It is a third-party library that can be used as a more concise and user-friendly alternative to the native XMLHttpRequest object for performing asynchronous requests.

Here are some differences between Ajax and Axios:

1. Grammar differences: Ajax uses native JavaScript syntax, while Axios adopts the syntax style of Promise, making the code simpler and easier to read.
2. Support differences: There are some differences in support for Ajax between different browsers, requiring some compatibility handling. However, Axios is a third-party library independent of the browser, allowing it to be used in different environments with better compatibility.
3. Rich functionality: Axios is more powerful than Ajax, as it offers a wider range of features such as intercepting requests and responses, transforming request and response data, and canceling requests. These capabilities make it easier for developers to handle and manage HTTP requests.
4. Chained calls: Axios supports chained calls, which allows handling the results of requests and responses using the .then() method. This approach makes the code structure clearer and easier to maintain.

Generally speaking, Axios is a more modern and powerful HTTP client compared to Ajax, with better compatibility and easier to use. For developers, Axios offers more features and a better development experience.
