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.
You may already be familiar with the basic features of the Chrome Developer Tools: the DOM inspector, styles panel, and JavaScript console. But there are a number of lesser-known features that can…
jQuery is a fast, small, and feature-rich JavaScript library. It makes things like HTML document traversal and manipulation, event handling, animation, and Ajax much simpler with an easy-to-use API that works across a multitude of browsers.

This is post # 11 of the series dedicated to exploring JavaScript and its building components. In the process of identifying and describing the core elements, we also share some rules of thumb we use…
We have extended our previous benchmarks to include other popular DOM manipulation libraries: Angular 1 and 2, Mithril.js, cito.js and the standalone independent implementation of React's Virtual DOM algorithm. We have also added more metrics (including memory use).
D3.js is a JavaScript library for manipulating documents based on data. D3 helps you bring data to life using HTML, SVG and CSS. D3’s emphasis on web standards gives you the full capabilities of modern browsers without tying yourself to a proprietary framework, combining powerful visualization components and a data-driven approach to DOM manipulation.

Enter COWS Ajax and many Possibilities become available. Allowing a connection to foreign sites can lead to the creation of a new breed of powerful tools and favelets. Instead of each site owner making their own tools, now a single author can make and distribute a cool tool or service that is easily installed on countless sites with the simple addition of one or two lines of code. It's extremely easy to install for a site owner, can provide extremely powerful apps to the users, and can provide extremely good branding or revenue for a tool creator.
