+***nodash*** offers you a rich set of library functions, comparable to
+the likes of [***underscore***](http://underscorejs.org/)
+or [***lodash***](https://lodash.com/).
+The functions are actually derived
+from the [***Haskell Prelude***](https://hackage.haskell.org/package/base-4.7.0.0/docs/Prelude.html)
+and emphasize a functional programming style.
+
+A special
+trait of this library is that it discards some JavaScript concepts (like
+`this`) to allow some (in the authors opinion) more useful ones. Every function
+from this library can be thought of as *curried*, i.e. you can partially apply
+any function and get a function in return (on the other hand this means there are
+no optional arguments). Also you have a distinction between *lists* and *streams*
+and it can cope with *infinite streams*.
+
+Browse through the [tests](https://github.com/scravy/nodash/tree/master/test) for examples.
