+``` coffeescript
+# CoffeeScript is a hipster language.
+# It goes with the trends of many modern languages.
+# So comments are like Ruby and Python, they use hashes.
+
+###
+Block comments are like these, and they translate directly to '/ *'s and '* /'s
+for the resulting JavaScript code.
+
+You should understand most of JavaScript semantices
+before continuing.

+# Assignment:
+number   = 42 #=> var number = 42;
+opposite = true #=> var opposite = true;
+
+# Conditions:
+number = -42 if opposite #=> if(opposite) { number = -42; }
+
+# Functions:
+square = (x) -> x * x #=> var square = function(x) { return x * x; }
+
+# Ranges:
+list = [1..5] #=> var list = [1, 2, 3, 4, 5];
+
+# Objects:
+math =
+  root:   Math.sqrt
+  square: square
+  cube:   (x) -> x * square x
+#=> var math = {
+#  "root": Math.sqrt,
+#  "square": square,
+#  "cube": function(x) { return x * square(x); }
+#}
+
+# Splats:
+race = (winner, runners...) ->
+  print winner, runners
+
+# Existence:
+alert "I knew it!" if elvis?
+#=> if(typeof elvis !== "undefined" && elvis !== null) { alert("I knew it!"); }
+
+# Array comprehensions:
+cubes = (math.cube num for num in list) #=> ...
