Problem Statement
What is the difference between a local component and a global component in Vue.js?
Explanation
Global components are registered once (e.g., app.component in Vue 3 or Vue.component in Vue 2) and can be used anywhere. Local components are registered in the components option of a specific parent and are only available within that component’s template subtree. Prefer local registration for better tree-shaking and to avoid name collisions; use global registration for UI primitives used across many views.

// Global (Vue 3)
import { createApp } from 'vue'
import Button from './Button.vue'
const app = createApp(App)
app.component('BaseButton', Button).mount('#app')
// Local
export default { components: { BaseButton } }
