What is Memory Leak?
A bug where an application keeps using more and more memory over time because it fails to release unused data.
Why It Matters
Memory leaks slowly degrade performance and can eventually crash your application.
Real-World Example
A web app that gets slower the longer you use it because event listeners are added but never removed.
“Understanding terms like Memory Leak matters because it helps you have better conversations with developers and make smarter decisions about your software. You do not need to be technical. You just need to know enough to ask the right questions.”
