In JavaScript, managing asynchronous tasks is essential for smooth applications. Hereโ€™s a quick breakdown:

๐Ÿ” Microtasks

  • Examples: Promise callbacks, MutationObserver.
  • Priority: Higher than macrotasks.
  • Execution: Runs after the current task and before the next event loop iteration.

โณ Macrotasks

  • Examples: setTimeout, setInterval.
  • Priority: Lower than microtasks.
  • Execution: Runs after the microtask queue is empty, starting a new event loop iteration.

๐Ÿ› ๏ธ Why It Matters
Understanding these concepts helps optimize performance and manage asynchronous operations effectively. Remember, promises resolve before any macrotasks execute!
