Performance tracking of VDOM updates with Vue Devtools

Explore the use of Vue Devtools to visualize and analyze the VDOM diffing process during component updates.

<template>
  <div>
    <button @click="updateMessage">Update Message</button>
    <p>{{ message }}</p>
  </div>
</template>

<script>
export default {
  data() {
    return {
      message: 'Hello World!'
    };
  },
  methods: {
    updateMessage() {
      this.message = 'Updated message at ' + new Date().toLocaleTimeString();
    }
  }
};
</script>

This Vue component includes a button that triggers an update of the 'message' data property when clicked. Vue Devtools can be used to track the VDOM changes when the message is updated.

<style>
button {
  margin: 10px;
  padding: 5px 15px;
}
p {
  color: #333;
}
</style>

The accompanying CSS styles the button and paragraph elements for better visual presentation.
