Say what you want about whether this is a good idea or not, it is clear at least part of MS is really serious about open source. * TypeScript is under the Apache 2.0 license [1] * Source is available via git on Codeplex [2] * Installation is as easy as npm install -g typescript [3] Extra bonus coolness: They've provided an online playground like jsfiddle!
