AJAX calls can be made with raw JavaScript, but this can be challenging since different browsers have different AJAX implementation syntaxes.

Writing regular ajax calls might become tedious when a web application uses multiple forms of Ajax calls, such as both synchronous and asynchronous calls, or different response formats, such as string messages, HTML, XML, and JSON.

However, if you combine jQuery and AJAX, you can leverage AJAX with minimal effort. If you use jQuery, you can create AJAX functionality with just one line of code.

You should have a better understanding of HTTP methods and API calls when you are using these AJAX methods. So, let’s discuss HTTP methods and see what is an API call is.

HTTP Methods

The Hypertext Transfer Protocol (HTTP) is designed for clients and servers to communicate with each other. HTTP is a request-response protocol that communicates between a client and a server. A client (browser) sends an HTTP request to the server, and then the response is sent by the server to the client. The response may include the requested content as well as status information about the request.

POST, GET, PUT, PATCH, and DELETE is the most used HTTP methods.

• POST - used to send data to the server
• GET - used to retrieve information from the given server.
• PUT – used to update an existing resource
• PATCH – used to make a partial update on a resource.
• DELETE - used to delete a resource.

Now let’s understand what an API call is.
