Problem Statement
What are props in Vue and how do you declare and use them?
Explanation
Props are read-only inputs passed from a parent to a child component. Declare them in the child with name, type, and optional default/validator. Use kebab-case in templates and camelCase in JavaScript. Props enable one-way data flow and component reuse.

// Child.vue
<script>
export default {
props: {
title: { type: String, required: true },
count: { type: Number, default: 0 }
}
}

<Child :title="'Hello'" :count="3" />
