Hook (computer science)

A hook in computer science is like a little special button that can be pressed to make certain things happen automatically. Think of it like a magic wand that can make your computer do things without you having to do them manually every time.

For example, imagine you always forget to save your work while typing a long essay. You can create a hook that automatically saves your work every few minutes so you don't have to worry about accidentally losing anything. Or if you want a special notification to pop up whenever someone sends you an email, you can create a hook that triggers the notification.

Hooks can be very helpful for making your computer do things more efficiently and saving you time. But you have to know how to create them and what they are capable of doing, just like a magician has to know how to use their wand properly.
