How does Node.js enhance server-side web development in 2024?.

Node.js enhances server-side web development through its asynchronous, event-driven architecture, which allows for handling multiple connections simultaneously without blocking the server. This results in improved performance and responsiveness for web applications. Additionally, Node.js uses JavaScript, making it easier for developers to work across both front-end and back-end environments.
