How to avoid vuex over reactivity?

[Sociopacific]

What problem does this feature solve?

If the getter returns an object or an array, this causes a recalculation of the properties that depend on this getter, even if the data in the object that returned the getter did not change. Can I somehow return the result of a previous getter calculation if the data has not really changed?

What does the proposed API look like?

someGetter(state, getters, rootState, rootGetters, oldValue) { ... if (JSON.stringify(result) === JSON.stringify(oldValue)) return oldValue; return result; }
