Vue Js
What is Vue.js?
Vue.js (pronounced as view) is a progressive JavaScript framework used for building user interfaces and single-page applications (SPAs). It was created by Evan You in 2014 and has since become one of the most popular front-end frameworks, alongside React and Angular.
The word “progressive” means you can use Vue for small parts of a website (like a widget) or scale it up to build large, complex web applications.
Why Use Vue.js?
✅ Easy to Learn – Beginner-friendly compared to React or Angular.
✅ Lightweight – Small size (~20KB) but powerful.
✅ Reactive Data Binding – UI updates automatically when data changes.
✅ Component-Based – Applications are built with reusable components.
✅ Great Documentation – Vue has one of the best and most detailed docs.
✅ Flexibility – Can be used for simple projects or enterprise apps.
