Code - Add two numbers and return sum

Times asked 1
Official solution

SimpleVue = UI ka smart assistant. Data badlo, screen khud update. MAD1 Jinja har click pe naya HTML.
Progressive frontend framework. Components, reactivity, directives.
MAD2 SPA: ek index.html, Vue Router pages, Flask sirf JSON.
Fayde: easy, SFC, docs. Vs React: templates HTML-like, course sikhata hai. Vs plain JS: baar-baar DOM mat chhedo.
Example
```

<template>
  <h1>{{ msg }}</h1>
</template>
<script>
export default { data() { return { msg: 'Hello' } } }
</script>
```
Project example: Navbar.vue + views (Login, Dashboard). data() / setup() reactive. fetch APIs.
Viva tipFayde: easy, SFC, reactivity. Vs React: chhota learning curve. Vs plain JS: UI state auto-update.

Advice: Helpful
