Svelte · Senior · Question 6 of 75

What happens with updates batched in Svelte 5?

count = 1;
count = 2;
name = "Ann";

✓Correct answer: Effects run once, in a microtask after the synchronous code, with the final values
2The DOM is updated three times synchronously
3Only the last assignment is kept; the others are ignored even in code

Explanation

Batching avoids wasted work and intermediate states. flushSync() applies updates immediately when needed.
