Svelte
Svelte
Svelte is a radical new approach to building user interfaces. Whereas traditional frameworks like 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. We're proud that Svelte was recently voted the most loved web framework with the most satisfied developers in a pair of industry surveys. We think you'll love it too. Read the introductory blog post to learn more. Svelte is a tool for building fast web applications. It is similar to JavaScript frameworks such as React and Vue, which share a goal of making it easy to build slick interactive user interfaces. But there's a crucial difference: Svelte converts your app into ideal JavaScript at build time, rather than interpreting your application code at run time.Starting Price: Free -

When working on a web application that involves a lot of JavaScript, one of the first things you learn is to stop tying your data to the DOM. It's all too easy to create JavaScript applications that end up as tangled piles of jQuery selectors and callbacks, all trying frantically to keep data in sync between the HTML UI, your JavaScript logic, and the database on your server. For rich client-side applications, a more structured approach is often helpful. With Backbone, you represent your data as Models, which can be created, validated, destroyed, and saved to the server.Starting Price: Free -
