Event Loop & Microtasks

What pattern does this code demonstrate?

const nextTick = () => new Promise(resolve => setTimeout(resolve, 0));

async function task() {
  console.log('Start');
  await nextTick();
  console.log('End');
}

task();
console.log('Sync');

Task scheduling
Error handling
Yielding to the event loop
This demonstrates yielding to the event loop: 1) Uses setTimeout(0) to create a macrotask, 2) Allows other tasks to execute between operations, 3) Prevents blocking the main thread, 4) Useful for breaking up long computations, 5) Common pattern in cooperative scheduling, 6) Important for maintaining UI responsiveness.
