<script lang="ts">
export let transition:
| {
duration?: number;
}
| undefined = undefined;
if (transition) {
// transition.duration should not be inferred as any but number
transition.duration = transition.duration ?? 1500;
}
</script>
What did you expect to happen?
transition.duration should be inferred as number.
If you look at transition.ts in the reproduction, you'll see it works correctly for .ts files, so it seems to be an issue with .svelte files.
What actually happened?
transition.duration is inferred as any.
