Answer
async/await enables writing asynchronous code in a synchronous style, avoiding callback complexity.
It improves scalability by freeing threads during I/O waits.
Quick Answer
async/await lets you write non-blocking code that reads like normal sequential code. Without it, async operations required callbacks or manual thread management. With it, the compiler generates a state machine that suspends and resumes execution automatically. Crucial for scalable web APIs and responsive UIs.
