How do worker threads differ from child processes?
Model answer
Worker threads run JavaScript in separate threads within the same process and can share memory through SharedArrayBuffer, which is good for CPU-heavy tasks. Child processes are separate OS processes with their own memory that communicate by messages, which is better for isolation or running other programs.
