Hooks, in their various forms, serve critical functions across multiple fields such as fishing, software development, and household tasks. This article will delve into the different types of hooks and their unique applications.

Materials and Sizes
Fishing hooks can be made from steel, bronze, or stainless steel and come in different sizes, suitable for both freshwater and saltwater fishing.
2. Hooks in Programming
In programming, a hook is a concept that allows the programmer to intercept or modify the operation of a system or application. This is commonly seen in web development and various software frameworks.
Types of Programming Hooks
