On this page:

http://synonym.dartlang.org/

There is this example:

var name = 'Bob';
name instanceof String // == true

In JS that evaluates to false not true. This is a good illustration of JS quirks:

var color1 = new String("green");
color1 instanceof String; // returns true
var color2 = "coral";
color2 instanceof String; // false
