Javascript instanceof WHATEVER
Pointless revelation of the morning:
function Foo() {}
var fooInstance = new Foo();
var Bar = Foo;
var Baz = Bar;
if (fooInstance instanceof Foo) {} // true
if (fooInstance instanceof Bar) {} // true
if (fooInstance instanceof Baz) {} // true
Not that this is particularly helpful in any way, but interesting enough to a groggy morning brain (it doesn't take much).
