::This is essentially a JavaScript version of [https://developer.mozilla.org/en/SpiderMonkey/JSAPI_Reference/JSClass.convert JSClass.convert], and is called when SpiderMonkey needs to coerce ''wrappee'' to a different type. ''type'' is a string identifying the name of the desired type to coerce to, and can be anything ordinarily returned by JavaScript's ''typeof'' operator. The default implementation of this is to call ''wrappee.''<code>valueOf()</code>. | |||

::This is essentially a JavaScript version of [https://developer.mozilla.org/En/SpiderMonkey/JSAPI_Reference/JSPropertyOp JSClass.delProperty]; alternatively, it could be described as the analog of Python's <code>__delattr__</code> magic method. ''name'' is the name of the property being deleted. This function should return <code>true</code> if the property can be deleted, and <code>false</code> if not. | ::This is essentially a JavaScript version of [https://developer.mozilla.org/En/SpiderMonkey/JSAPI_Reference/JSPropertyOp JSClass.delProperty]; alternatively, it could be described as the analog of Python's <code>__delattr__</code> magic method.
