PureScript 是个小巧而强大的静态类型语言，可以编译成 JavaScript。purescript 主要是由 Haskell 和 PureScript 编写的。 v0.10.0-rc.1 更新内容如下： 主要变化： The new functional dependencies feature fixes type inference in some cases involving multi-parameter type classes. However, due to a bug in the compiler, some of those expressions were previously type checking where they should not have. As a result, it is necessary to add functional dependencies to some classes in order to make previous code type-check in some cases. Known examples are: MonadEff and MonadAff MonadState, MonadReader, and the rest of the MTL-style classes in transformers These libraries will be updated before the final release of 0.10.*, but you might experience some issues in the meantime. 新功能： Data.Newtype Deriving It is now possible to derive the Newtype class for any data declaration which is a newtype, using the existing deriving instance syntax: newtype Test = Test String derive instance newtypeTest :: Newtype Test _ Note that the second type argument should be specified as a wildcard, and will be inferred. 完整版更新内容请查看：https://github.com/purescript/purescript/releases 下载地址： linux64.sha linux64.tar.gz macos.sha macos.tar.gz Source code (zip) Source code (tar.gz) PureScript v0.10.0 rc1 发布，静态类型语言下载地址
