I have a question

[qqf]

If all the items in the list are selected, then click toggle-all should all be unchecked?

I don't understand this line of code in the src/store/mutations/todo.js file.

const areAllCompleted = state => state.length && selectCompleted(state).length === state.length;

maybe it should be

const areAllCompleted = ({ todos }) => todos.length && selectCompleted(todos).length === todos.length;

I am just explaining my idea, thank you very much for this project, I can learn Vue3 through it.
