In JavaScript, managing asynchronous tasks is essential for smooth applications. Hereβs a quick breakdown:
π Microtasks
- Examples: Promise callbacks,
MutationObserver
. - Priority: Higher than macrotasks.
- Execution: Runs after the current task and before the next event loop iteration.
β³ Macrotasks
- Examples:
setTimeout
,setInterval
. - Priority: Lower than microtasks.
- Execution: Runs after the microtask queue is empty, starting a new event loop iteration.
π οΈ Why It Matters
Understanding these concepts helps optimize performance and manage asynchronous operations effectively. Remember, promises resolve before any macrotasks execute!
