Loupe is a tool for visualizing the JavaScript runtime at runtime, rendering how the event loop, call stack, callbacks, promises, and timers interact as your code executes. It is primarily used as an interactive teaching aid for understanding JavaScript's asynchronous execution model.
Use cases
- understand how the javascript event loop works
- visualize async callbacks and promise execution order
- teach javascript concurrency to students
- debug why code runs in an unexpected order
- learn how setTimeout and the call stack interact
When to choose
- you are learning or teaching JavaScript's asynchronous runtime behavior
- you want a step-by-step visual trace of event loop execution
When to avoid
- you need a production debugging or profiling tool
- you need actively maintained software with a license and ongoing support
