Why Gin?

One of the best features of Go is its built-in net/http library that allows you to create an HTTP server effortlessly. However, it is also less flexible and requires some boilerplate code to implement.

There is no built-in support in Go to handle routes based on a regular expression or a "pattern". You can write code to add this functionality. However, as the number of your applications grows, it is quite likely that you will either repeat such code everywhere or create a library for reuse.

This is the crux of what Gin offers. It contains a set of commonly used functionalities, e.g. routing, middleware support, rendering, that reduce boilerplate code and make writing web applications simpler.
