By Anatoly Mironov
If you develop much javascript and css, this is the exension to Visual Studio you just can’t live without: Web Essentials (It is even released for VS2012). You can do many things with it. Here are two examples for simple but very useful functions: 1. Show which browsers support a css attribute: 2.

And it is fully appliable in SharePoint development.
Less and Coffeescript
Now using less and coffeescript (update: and typescript) can be really easy even in SharePoint. Whenever you save a .less file or .coffeescript, it will create a corresponding file with .css or .js file extensions in the same folder.

UPDATE: For some reason the css is not generated when I run Visual Studio 2012 on Server 2008 with Web Essentials, but it works fine on my Windows 8 machine. To play around with less, you can use this demo site (creds to @irishbuzz on so). Next: Typescript and SharePoint
