What is Stelve?. Stelve is one of the latest JavaScript… | by Diego Perez | August 2022

Stelve is one of the latest JavaScript frameworks for building user interfaces. Compared to other web development tools such as Vue, Angular, or React, which perform most of the workload in the browser, Stelve performs build-in-deployment to speed up code loading.

The framework’s popularity has grown in recent years, considered the most popular web framework with the most satisfied developers in surveys conducted by StackOverflow.

No virtual DOM

The main difference is that Svelte is a framework that does not need to use the virtual DOM, which allows React to store the DOM element tree in memory, and when updating in a component , only the specific component is rendered, however, this DOM manipulation process slows down the web application.

Instead, Svelte avoids using the virtual DOM by leveraging its compilation step to wrap state and property changes in functions that can update the DOM in a specific way.

Syntax

Svelte has a concise, easy and simple syntax for building component-based applications. Its syntax reduces the amount of code to write, where the code in a React component can be around 40% larger than its equivalent in Stelve.

Conclusion

Svelte is a tool that will help you create interactive user interfaces, which convert your application to JavaScript at compile time, instead of interpreting code at run time in the browser. This way, there are no performance costs or penalties when loading the application for the first time.
