What is Vue?

• Definition: A JavaScript and TypeScript framework for creating interactive web apps and SPAs.
• Usage: Can create standalone widgets (e.g., search bar, contact form) or full websites.
• DOM Interaction: Simplifies user interaction and state management, enabling dynamic UI updates.
• Data-Driven Websites: Ideal for creating interactive, data-driven websites.

How Vue Works

• Stand-Alone Widgets: Create components that can be reused in multiple HTML pages.
• Full Websites: Use Vue for SPAs, handling routing in the browser.
  • Traditional websites request new HTML from server for each page.
  • Vue SPAs send a single HTML page, with Vue handling routing and rendering in-browser.
