beedle/demo/advanced/js/store/mutations.js

Beedle is a tiny little library to help you manage state across your application. Inspired by great libraries like Vuex and Redux, Beedle creates a central store that enables you to both better control and cascade state across your application.

export default {
    addItem(state, payload) {
        state.items.push(payload);
        
        return state;
    },
    clearItem(state, payload) {
        state.items.splice(payload.index, 1);
        
        return state;
    }
};
