Why would anyone build with this?

REASON 1

Parse an HTML form POST request straight into a typed Go struct instead of manually converting strings.

REASON 2

Build a user registration endpoint that turns submitted name, age, email, and phone fields into a User struct.

REASON 3

Convert a Go struct back into URL-encoded form data to send in a request.

REASON 4

Handle nested form fields like arrays of addresses or maps of settings via naming conventions.
