Answer
Asynchronous programming allows Node to run tasks without waiting, improving scalability.
Quick Answer
Asynchronous programming means starting an operation (file read, database query, API call) and continuing to do other work while waiting for it to finish. When the operation completes, the callback, Promise, or async/await resumes. This is how Node.js serves many requests simultaneously with one thread — nobody waits for nobody.
