Why It Matters

Vue's gentle learning curve and excellent documentation make it the most accessible framework for beginners, while its ecosystem supports large-scale applications.

<script src="https://unpkg.com/vue@3/dist/vue.global.js"></script>

<div id="app">
  <h1>{{ message }}</h1>
  <button @click="count++">Clicked {{ count }} times</button>
</div>

<script>
  const { createApp, ref } = Vue;
  createApp({
    setup() {
      const message = ref("Hello Vue!");
      const count = ref(0);
      return { message, count };
    }
  }).mount("#app");
</script>

Expected output: A page displaying "Hello Vue!" and a button that increments and displays click count.
