How to: ![✔] 7.1. Don't block the event loop
**TL;DR:** Avoid CPU intensive tasks as they will block the mostly single-threaded Event Loop and offload those to a dedicated thread, process or even a different technology based on the context.

**Otherwise:** As the Event Loop is blocked, Node.js will be unable to handle other request thus causing delays for concurrent users. **3000 users are waiting for a response, the content is ready to be served, but one single request blocks the server from dispatching the results back**
