What is Web Worker?
A way to run JavaScript code in the background without blocking the main page from responding to users.
Why It Matters
Web workers keep your UI responsive during heavy computations by running them on a separate thread.
Real-World Example
Processing a large CSV file in a web worker so the page stays responsive while the data is being parsed.
“Understanding terms like Web Worker 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.”
From definition to deployment
Knowing the term is step one. Using it in something real is the rest.
