What is the difference between spawn() and exec() in the child_process module?

Accepted Answer

The difference between spawn() and exec() lies in how they handle output. exec() buffers the output in memory and returns it in a callback, while spawn() streams the output, making it more suitable for large outputs or long-running processes.
