[[
throws a TypeError. 
]]

In general RangeErrors are better used when only an enumeration should be allowed and you want to throw when outside that range. See e.g. http://people.mozilla.org/~jorendorff/es6-draft.html#sec-string.prototype.normalize
Comment 1 Anne 2014-11-05 12:46:06 UTC 
String.prototype.normalize was defined after IDL enumerations which use TypeError...
Comment 2 Domenic Denicola 2014-11-05 12:54:13 UTC 
Hmm yeah this conversation is starting to feel familiar...

I will try to PR WebIDL to use RangeError and see where that discussion goes.
