+## Variables and Scope
+
+Variable assignment is always local to the scope of the function in which it is declared. To explicitly declare a global variable, either directly setting it as a property on the global object:
 
+```coffeescript
+# in browsers
+window.foo = "bar"
+```
+or with the following pattern:
+
+```coffeescript
+exports = this
+exports.foo = "bar"
