This is analog with the JS builtins (like Date.prototype.getFullYear) 92253 1 bzbarsky 2013-08-19 06:11:36 +0000 WebIDL says nothing about these having a "prototype" own property, so they have nothing there in particular, which matches the implementations... Maybe I'm missing what this bug is about? 92331 2 erik.arvidsson 2013-08-20 14:21:09 +0000 Functions have a prototype property by default. I would like the spec to point out that the functions backing operations are not normal functions and should not have a prototype (same for the getter and setter functions). 92334 3 erights 2013-08-20 14:46:45 +0000 (In reply to comment #2) > Functions have a prototype property by default.

I agree they should not have a prototype property or a [[Construct]] internal method. But I would avoid the phrase "not normal functions". In ES3 and ES5, all non-constructor Chapter 15 functions are of this form. In ES6, arrow functions are as well. 92336 4 d 2013-08-20 15:08:57 +0000 I believe ES6 methods do not have `prototype` properties or [[Construct]] internal methods, at least per the non-normative prose [1]. Thus it would suffice to say that WebIDL methods should be created in the same way as ES6 methods.
