There is a “class” keyword (which was therefore a “future reserved word” 
until then [1]), and the parts of the code that it declares *are* classes in 
that language:

<http://people.mozilla.org/~jorendorff/es6-draft.html#sec-ecmascript-language-functions-and-classes>

The classes of the ES 4 Draft [2], which was implemented by some in 
production quality [3][4], are different at least in the fact that built-in 
types are classes as well.

That depends on how you define “class”.  The same as it is unreasonable to 
define OOP solely by the features of OOP present in, e.g., Java, it is 
unreasonable to define “class” only as it is used elsewhere, and then deny 
the existence of “classes” or “full support for classes” in an (draft) 
Edition of ECMAScript.
