Handle async operations with promises and async/await
Why asynchronous code matters
Understanding the difference
How JavaScript handles async
Schedule code to run later
Defer to next event loop tick
Pass functions to handle results
Node.js callback convention
The problem with nested callbacks
A better way to handle async
Make your own promises
Pending, fulfilled, rejected
Handle fulfilled promises
Chain async operations
Handle rejected promises
Run cleanup code always
Create already-settled promises
Run promises in parallel
Get the first settled promise
Wait for all regardless of outcome
Write async code that looks sync
Pause for promise resolution
Compare the two styles
Use try/catch for async errors
Await multiple promises together
Avoid these mistakes
Use await at module level
Make HTTP requests
Configure HTTP requests
Check response status
Process async data streams
Control async operation frequency
