<h4>What is Vuex?</h4>
<p>Vuex is a state management pattern + library for Vue.js applications.</p>
<div class="app">
    <p>{{ count }}</p>
    <p>
        <button @click="increment">+</button>
        <button @click="decrement">-</button>
    </p>
</div>

        },

            increment: state => state.count++,
            decrement: state => state.count--
        }
    })
