Svelte Components
Svelte Components are the building blocks of Svelte applications, encapsulating reusable UI elements with HTML, CSS, and JavaScript in a single .svelte file. They use a declarative syntax and compile away the framework at build time, resulting in highly efficient vanilla JavaScript code. This approach eliminates the need for a virtual DOM, making components lightweight and fast.
Developers should learn Svelte Components when building interactive web applications that require high performance and minimal runtime overhead, such as real-time dashboards, data visualizations, or progressive web apps. They are ideal for projects where bundle size and speed are critical, as the compile-time optimization reduces client-side JavaScript and improves initial load times.
