Welcome to your interview.
The question is on your right: Main Thread vs Worker Threads. Take a moment with it first.
Talk your thinking through with me if you like - when you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes). Discussion and graded submissions share your five interviewer interactions, so spend them well.
Explain the JavaScript main thread and worker threads. How do you communicate between the main thread and worker threads, and how can worker threads impact the main thread?
