#### CoffeeScript Family (& Friends)

* [[CoffeeScript|http://jashkenas.github.com/coffee-script/]] Unfancy JavaScript

###### Family (share genes with CoffeeScript)

* [[Coco|https://github.com/satyr/coco]] A CoffeeScript dialect that aims to be more radical and practical, also acts as a test bed for features that get imported in CoffeeScript.
    * [[LiveScript|http://gkz.github.com/LiveScript/]] is a fork of Coco that is much more compatible with CoffeeScript, more functional, and with more features.

Methods of Signing with GPG

Last updated March 28, 2021

There are now two ways to approach this:

1. Using gpg and generating keys
2. Using Kryptonite by krypt.co

This Gist explains how to do this using gpg in a step-by-step fashion. Kryptonite is actually wickedly easy to use-but you will still need to follow the instructions

Current

SuperCall : super Arguments

1. Let newTarget be GetNewTarget().
2. Assert: Type(newTarget) is Object.
3. Let func be ? GetSuperConstructor().
4. Let argList be ? ArgumentListEvaluation of Arguments.
5. Let result be ? Construct(func, argList, newTarget).

var p = Promise.resolve(1).then(v => console.log(v);
                                
console.log(0);

await import('foo');

console.log(2);

p.then(() => console.log(3);

The WeakRef Constructor
https://tc39.github.io/proposal-weakrefs/#sec-weak-ref-constructor

- [ ] is the initial value of the WeakRef property of the global object.
- [ ] is designed to be subclassable. It may be used as the value in an extends clause of a class definition. Subclass constructors that intend to inherit the specified WeakRef behaviour must include a super call to the WeakRef constructor to create and initialize the subclass instance with the internal state necessary to support the  WeakRef.prototype built-in methods.

WeakRef ( target )
https://tc39.github.io/proposal-weakrefs/#sec-weak-ref-target

1. [ ] If NewTarget is undefined, throw a TypeError exception.
