Async/await patterns that make JavaScript readable

async/await makes asynchronous code look synchronous, but there are still traps if you're careless.

# Parallelize when you can

If tasks are independent, use Promise.all instead of sequential awaits to cut waiting time significantly.

# Always handle errors

Wrap awaits in try/catch or handle them at the right layer; a forgotten promise can swallow an important error.

• Avoid await in loops when unneeded
• Use Promise.allSettled when partial failure is fine
• Set timeouts for network work

Clear async code is code you can trust.
