• JavaScript Frameworks: Libraries like React, Vue.js, and AngularJS handle UI rendering and data manipulation on the client side.
• APIs: SPAs communicate with servers through APIs to fetch and update data without full page reloads.
• Single-Page Architecture: The entire application logic resides within a single HTML document, with content updated dynamically.
