Worker Threads

• use to perform heavy JavaScript tasks
• use to run code in parallel
• runs in isolation but has ability to pass information between it and the parent Worker
• connected to parent worker via message channel
  • parentPort.postMessage() - send message to parent
  • worker.postMessage() - send message to child
• data is clone and not in shared memory
• best not to use for I/O operations; Node.js native I/O mechanisms are way faster
