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。
PureScript 0.6.9 发布，此版本现已提供下载。
更新内容如下：
重大改进
refEq and refIneq are no longer exported from the Prelude.
Bug 修复
Instances can now be defined before the corresponding class declaration (@paf31)
A bug related to imports in psci was fixed. (@paf31)
A typechecker bug related to type class dictionaries was fixed. (@garyb)
A bug related to operator precedence in codegen was fixed. (@garyb)
功能增强
psci now supports long-form directives (@mrhania)
Syntax for imports and other declaration types in psci was improved. (@hdgarrood)
Markdown comments can now be included at the module level (@joneshf)
Error messages are now represented internally as an algebraic data type, and pretty printing has been improved by using the boxes library. Errors now link to the wiki. (@paf31)
psc-docs can now generate tags files for Vim and Emacs (@jacereda)
psci now supports a --node-opts flag for passing options to the Node executable. (@MichaelXavier)
Code gen now preserves names of more function arguments in case statements (@andyarvanitis)
文档
The Prelude now has Markdown documentation (various contributors - thank you!)
The Pursuit website has been updated with new versions of libraries, including Markdown documentation (@hdgarrood)
库
The following libraries are now core libraries:
purescript-tailrec - A type class for monadic tail recursion
purescript-monad-eff - A type class for monads supporting native effects
purescript-integers - Integer numeric type
purescript-invariant - Invariant functors
purescript-parallel - An applicative functor for parallel composition of asynchronous computations
其他
There is an experimental C++11 backend for PureScript called pure11.
