JavaScript is a famous scripting language that requires requests to the server side. The language has various methods, including GET, POST, DELETE, PUT, COPY, PATCH, and HEAD, to create HyperText Transfer Protocol (HTTP) requests. These requests are employed to make the interaction between the server and clients. Based on these HTTP requests, users can send or receive data/information from the server.

In this article, the key difference between GET and POST requests is discussed under the umbrella of HTTP requests. Both these requests are utilized to transform information between websites and servers. The vanilla term is used as simple JavaScript without using additional frameworks and libraries.
