1. 등장배경

Front-end frameworks like Vue.js and React.js have arisen primarily to address the challenges and complexities of building modern web applications. These frameworks provide a structured and efficient way to manage the user interface (UI) of web applications. Here are some reasons why these frameworks have become popular:

1. User Experience Demands: Modern web applications require dynamic and interactive user experiences. Users expect websites to be responsive, fast, and interactive, which can be challenging to achieve with traditional server-side rendering approaches.
2. Single Page Applications (SPAs): SPAs have gained popularity due to their ability to deliver seamless user experiences by dynamically loading content without full page reloads. This requires sophisticated client-side scripting, and frameworks like React and Vue provide the necessary tools to manage the complexity.
3. Component-Based Architecture: Front-end frameworks introduce the concept of component-based architecture. UI components encapsulate their own logic, styles, and behavior, making it easier to build and maintain large applications. This promotes code reusability and modularity.
4. Virtual DOM: React and Vue use a virtual DOM (Document Object Model) to efficiently update the UI by minimizing actual manipulations of the real DOM. This results in improved performance and a smoother user experience.
5. State Management: Modern web applications often have complex state management requirements. Front-end frameworks provide solutions to manage and synchronize application state across different components and views.
6. Declarative Syntax: Frameworks like React and Vue use a declarative syntax, which means developers describe what the UI should look like at any given point, rather than writing imperative code that directly manipulates the UI.
7. Community and Ecosystem: These frameworks have vibrant communities and ecosystems of libraries, tools, and resources that make development faster and more efficient.
8. Developer Experience: Front-end frameworks offer development tools, debugging capabilities, and hot-reloading features that enhance the developer experience and streamline the development process.

2. 기존기술 JSP와의 차이점

Comparing front-end frameworks to traditional server-side rendering approaches like JSP (JavaServer Pages):

1. Responsiveness: Front-end frameworks focus on creating responsive and interactive user interfaces, whereas traditional server-side rendering approaches might lead to slower user experiences due to full page reloads.
2. Complexity: Modern web applications are often more complex and dynamic, requiring frequent updates and interactions. Front-end frameworks provide a more organized and manageable way to handle this complexity through components and a virtual DOM.
3. Performance: Front-end frameworks' virtual DOM and optimized rendering processes can lead to better performance and reduced latency compared to server-side rendering, especially for SPAs.
4. Separation of Concerns: Front-end frameworks promote a clear separation of concerns between the client-side and server-side aspects of an application, leading to cleaner and more maintainable codebases.
5. Interactivity: Front-end frameworks make it easier to create interactive UIs, as they allow developers to manage UI changes without involving server-side logic.
6. Client-Side Rendering vs Server-Side Rendering: While server-side rendering generates fully rendered HTML on the server and sends it to the client, client-side rendering frameworks like React and Vue generate the HTML structure on the client side after fetching raw data from the server. This allows for dynamic updates and more interactive experiences.

In summary, front-end frameworks like Vue.js and React.js have emerged to address the challenges posed by modern web application requirements, providing tools and approaches that lead to more efficient development, better user experiences, and improved performance compared to traditional server-side rendering approaches like JSP.
