try/finally Without catch

Cleanup without handling

You can use try/finally without catch. The error still propagates up, but your cleanup code runs first.

function process() {
  try {
    doWork();
  } finally {
    cleanup(); // Runs before error propagates
  }
}

This pattern ensures cleanup happens even when you want errors to bubble up.
