5 Reasons Why Svelte Should Be Your Next JavaScript Framework

As web development continues to grow in popularity, developers have more options for choosing a JavaScript framework to build their applications. Svelte is one such framework that has gained a lot of attention in recent years. In this post, we will explore the top 5 reasons why Svelte should be your next JavaScript framework.

If you're curious about how SolidJS compares to Svelte, you might be interested in reading our write-up on SolidJS vs Svelte. In this article, we will explore the differences between these two frameworks and help you decide which one is best suited for your next web application project.

Simple Syntax

One of the most significant advantages of Svelte is its simple syntax. Unlike other frameworks that use complex syntax, Svelte uses a mix of HTML, CSS, and JavaScript to create components. This approach makes it easy for developers to understand and use Svelte.

Svelte's syntax is also very clean and concise, making it easy to read and maintain. With Svelte, developers can focus on building applications, rather than learning a new framework. This simplicity also makes it easier for developers to onboard and train new team members on Svelte.

Built-In Reactivity

Svelte's built-in reactivity is another feature that sets it apart from other frameworks. Reactivity refers to the ability of a framework to automatically update the DOM when data changes. With Svelte, developers don't have to manually update the DOM every time data changes. Instead, Svelte automatically updates the DOM when data changes, making the development process faster and more efficient.

This feature is especially useful when dealing with large datasets, as it eliminates the need for manual updates, which can be time-consuming and error-prone. With Svelte's reactivity, developers can write less code and focus more on building their application.

Fast Performance

Svelte's fast performance is another feature that sets it apart from other frameworks. Unlike React or Vue, Svelte doesn't use a virtual DOM to update the DOM when data changes. Instead, Svelte compiles the template into highly optimized JavaScript code during the build process. This results in a faster and more efficient rendering process, even on slower devices.

Smaller Bundle Sizes

Svelte's compilation process moves a lot of work to build-time, resulting in much smaller bundle sizes than other frameworks. This means your application will load faster, reducing the time your users spend waiting for it to render. Smaller bundle sizes also mean less data usage, which can be a significant benefit for users with limited data plans.

The smaller bundle sizes also make Svelte an excellent choice for building progressive web applications (PWAs). PWAs are web applications that have native app-like features, such as offline functionality and push notifications. With Svelte's small bundle sizes, PWAs built with Svelte are faster and more efficient, providing a better user experience.

Excellent Documentation

Svelte has excellent documentation that covers everything from the basics to advanced topics. The documentation is easy to understand, and it provides clear examples that make it easy to implement Svelte in your project. With excellent documentation, developers can easily learn how to use Svelte and take advantage of its many features.

Svelte's documentation is also updated frequently, reflecting changes to the framework and its best practices. This ensures that developers always have access to the most up-to-date information and resources.


Svelte is a powerful and efficient framework that offers many benefits for developers who want to build fast and scalable web applications. With its simple syntax, built-in reactivity, fast performance, smaller bundle sizes, and excellent documentation, Svelte is an excellent choice for your next JavaScript framework.

Svelte's ease of use and strong community support make it an excellent choice for building modern web applications. Whether you're an experienced developer or just starting, its simplicity and performance make it a framework worth considering.
