🧒 Explain like I'm 5
Imagine you have a big library. Cache-Aside is like checking a book out only when someone asks for it. Write-Through is like updating both the library and a notebook every time a book is borrowed. Write-Back is like writing in the notebook first and updating the library later. Each has its own pros and cons.
