What is Vue?

• Vue is a popular JavaScript and TypeScript framework for fast, reliable, interactive web apps and SPAs (Single Page Applications).
• Can create standalone widgets (e.g., search bar, contact form) or full websites.
• Simplifies interaction with the DOM and management of state and data.
• Enhances UI updates based on user actions (e.g., clicking buttons, typing inputs).

How Vue Works

Standalone Widgets

• Vue components can be used for widgets (e.g., signup form).
• Widgets are self-contained, reusable across different HTML pages.

Full Websites

• Creates Single Page Applications (SPAs).
• SPAs handle routing between pages in the browser instead of the server.
• Initial server request returns a minimal HTML page and Vue JavaScript bundle.
• Vue handles rendering components and routing in the browser.
• SPAs improve speed and smoothness of navigation.
