This is essentially how ES6 classes get wired up. Actually what they do is
closer to:
let tempProto = Object.create(B.prototype);
tempProto.constructor = function (<constructor params>) {<constructor body>);
tempProto.constructor.__proto__ = B;
tempProto.constructor.prototype = tempProto;
C=tempProto.constructor;
