Await, Without the Wait

await lets you pause inside an async function until a Promise settles, so async code reads like clear, top-to-bottom logic. It doesn’t block the thread; it yields to the event loop and resumes with the result (or throws on rejection).

Advantages

  • Clear, readable control flow (less callback/promise chaining)
  • Centralized error handling with try/catch/finally
  • Easier testing and maintenance
  • Fewer race-condition footguns when steps must be sequential

Disadvantages

  • Easy to accidentally serialize independent work (performance hit)
  • Array helpers like forEach don’t await (can cause subtle bugs)
  • Overuse (e.g., top-level or nested awaits) can slow startup
  • Requires explicit timeouts/cancellation to avoid hanging calls
