- Security Risks: Vulnerable to security issues like Cross-Site Scripting (XSS).
- Client-Side Resource Intensity: Places a heavy load on the client side, impacting older devices.
- Dependency on JavaScript: Essential functionality may break if users disable JavaScript.

- Complex Development: Developing SPAs is more complex, requiring a learning curve.
What is Single Page Application?
A Single Page Application (SPA) is a type of web application that loads and updates content dynamically without refreshing the entire page. Unlike traditional websites, SPAs use modern technologies to enhance the user experience by minimizing interruptions and providing a smoother interface. Users can interact with the application seamlessly, similar to using desktop software. The main advantage is the elimination of full-page reloads, resulting in a more responsive and engaging web experience. This is achieved by ensuring that the browser obtains all essential HTML, JavaScript, and CSS codes in one request or updates the necessary content based on user actions.
When you click on something in a SPA, it only sends the necessary information to your browser and the browser renders it. This is different from a traditional page load, where the server sends a full page to your browser with every click you make.
