There have been multiple thread on this and I did not know were to comment, so I'll add few comments here.
I think that whole constructors as classes business in JS is confusing for everyone coming to JS, and they only understand it after understanding confusing constructor- prototype relationship. It is true that people find var point = new Point(x, y) point instanceof Point intuitive but that's because it looks like Java. Also they are quite puzzled to find out that in some cases: var point = Point(x, y) works the same. On the other hand people may find Point.new(x, y) as intuitive, as they will think of ruby instead of java. Also, I do not think there is a point to use `constructor` with all it's confusing prototype relationships for initialization in "prototypes as classes", just use initialize method to do that. Is it really too late to undo `constructor` as classes ? There are other proposals like rest and spread with a hope that `arguments` will die off some day. Why this would be different ? Finally I believe that killing constructors will make js straight forward to understand and lighter in syntax.
