async/await is syntactic sugar over Promises. It lets you write asynchronous code that reads like synchronous code.

• Async Functions — Declaring async functions
• Await Keyword — Pausing execution for promises
• Error Handling — try/catch with async/await
• Parallel Execution — Using Promise.all with async/await
• Top-Level Await — Using await outside async functions

• async makes a function return a Promise
• await pauses until the Promise resolves
• Error handling uses try/catch
• Use Promise.all() for parallel operations
