Just as with the open sourced .NET, Microsoft intends to run ChakraCore's development as a proper community project. The company says that Intel and AMD have already expressed interest in contributing, and others are sure to join them. At release, the code will be Windows-only, but Microsoft will be working to make ChakraCore cross-platform—just as it did when making .NET open source.
ChakraCore could also find itself used in, for example, NoSQL database engines and as the integrated scripting language in game engines.
Update: Reports from the event say that Microsoft has now decided on the MIT license.
