Single Page Applications (SPA)

A Single Page Application (SPA) is a type of website or web app that loads just one webpage initially, then dynamically updates its content without needing to reload the entire page. This creates a smoother, faster user experience, similar to using a mobile app. SPAs use JavaScript to fetch and display data seamlessly, enabling features like real-time updates and interactive interfaces. Examples include Gmail and Facebook, which feel responsive and integrated, since they don't constantly load new pages but instead update parts of the existing page dynamically.
