declarationMap

我们还添加了对 声明源映射 的支持。如果启用 declarationMap，您将能够使用 "Go to Definition" 和重命名等编辑器功能在支持的编辑器中跨项目边界透明地导航和编辑代码。

We've also added support for declaration source maps. If you enable declarationMap, you'll be able to use editor features like "Go to Definition" and Rename to transparently navigate and edit code across project boundaries in supported editors.
