Worker Threads allow you to run JavaScript code in multiple threads and are ideal for tasks like data processing or computations.
Child Processes enable you to spawn separate processes to run tasks independently, making them suitable for tasks requiring isolation or working with non-JavaScript scripts or binaries.
Real-life use cases for Worker Threads include image processing, data parsing and transformation, and mathematical computations.
Real-life use cases for Child Processes include executing shell commands, running non-JavaScript scripts, and implementing microservices architecture.
