New ES6 constructor features and semantics: Alternative 2 manual super in derived classes

New ES6 Constructor Semantics and Usage Examples

Manual super: Alternative Design where subclass constructors do not automatically call superclass constructors

This Gist presents a new design of class-based object construction in ES6 that does not require use of the two-phase @@create protocol.

One of the characteristics of this proposal is that subclass constructors must explicitly super invoke their superclass's constructor if they wish to use the base class' object allocation and initialization logic.

An alternative version of this design automatically invokes the base constructor in most situations.

Tinder API Documentation

Tinder API documentation

Note: this was written in April/May 2014 and the API may has definitely changed since. I have nothing to do with Tinder, nor its API, and I do not offer any support for anything you may build on top of this. Proceed with caution

http://rsty.org/

I've sniffed most of the Tinder API to see how it works. You can use this to create bots (etc) very trivially. Some example python bot code is here -> https://gist.github.com/rtt/5a2e0cfa638c938cca59 (horribly quick and dirty, you've been warned!)
