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.
Following instructions from the excellent https://www.rinkeby.io/
A full node lets you access all state. There is a light node (state-on-demand) and wallet-only (no state) instructions as well,
CertSimple just wrote a blog post arguing ES2017's async/await was the best thing to happen with JavaScript. I wholeheartedly agree.
In short, one of the (few?) good things about JavaScript used to be how well it handled asynchronous requests. This was mostly thanks to its Scheme-inherited implementation of functions and closures. That, though, was also one of its worst faults, because it led to the "callback hell", an seemingly unavoidable pattern that made highly asynchronous JS code almost unreadable. Many solutions attempted to solve that, but most failed. Promises almost did it, but failed too. Finally, async/await is here and, combined with Promises, it solves the problem for good. On this post, I'll explain why that is the case and trace a link between promises, async/await, the do-notation and monads.
First, let's illustrate the 3 styles by implementing
