Svelte: Build lightning-fast web applications
Svelte is a radical new approach to building user interfaces. While React and Vue do the bulk of their work in the browser, Svelte shifts that work into a compile step that happens when you build your app. Instead of using techniques like virtual DOM diffing, Svelte writes code that surgically updates the DOM when the state of your app changes.
This results in smaller bundle sizes, improved performance, and a fantastic developer experience. If you're looking for a fast, efficient, and modern way to build web applications, hiring a Svelte freelancer could be the perfect solution.
What to look for in a Svelte freelancer
When hiring a Svelte freelancer, look for demonstrable experience building real-world applications. A strong understanding of core web technologies (HTML, CSS, and JavaScript) is essential, as is familiarity with SvelteKit, the official framework for building Svelte apps.
Experience with testing frameworks and state management solutions like Svelte stores is also highly desirable.
