Svelte is an open-source, component-based JavaScript framework that simplifies the process of building modern web applications.

Created by Rich Harris in 2016, Svelte stands out from other frameworks like React, Angular, and Vue by introducing a new paradigm that shifts the work from runtime to compile time.

Instead of shipping a runtime library to manage the application state and UI, Svelte compiles your components into highly efficient JavaScript code, resulting in faster load times and smoother user experiences.

Key Features of Svelte

  1. Compiler-centric Approach: Unlike most JavaScript frameworks, Svelte does not have a virtual DOM. Instead, it compiles your code into small, self-contained JavaScript modules. This eliminates the need for additional runtime libraries, resulting in faster, leaner applications.
  2. Reactive Programming: Svelte adopts a reactive programming model, allowing you to update the UI whenever the state changes automatically. By using simple assignment statements, Svelte creates efficient code that updates the UI without the need for explicit event listeners or complex state management libraries.
  3. Component-Based Architecture: Svelte promotes a modular approach to building web applications, where you can create reusable components with encapsulated styles and…
