|
|
* identity is used to look up the object, and not the value returned from calling <code>toString()</code> on it.

|
||
|
|
* var obj = new Object();
|

* dict[key] == "Letters"; // true
|
||
|
|
* obj["key"] == "Letters"; // true
|
||
|
|
* obj[key] == "Letters"; // true because key == "key" is true b/c key.toString == "key"
|
