Hi @tricaric! I'm Dosu and I’m helping the vueuse team.

This is expected: toReactive is designed for refs containing plain objects, not arrays. Internally, it creates a proxy with an empty object as the target, which means when you pass ref([]), the result is an object ({}), not an array ([]). This breaks array methods and can cause errors like the stack overflow you saw. If you want a reactive array, use reactive(ref([]).value) or just reactive([]) instead. The current API doesn't support array refs for toReactive—it's intended for objects only, as shown in the implementation and tests see source.

To reply, just mention @dosu.
