Standard Haskell: Ergonomics + Performance

He basically wants a language with a type system that lets you ensure that reading an element at an arbitrary position is safe and cannot crash because the index is always within the range of the array. He goes through all the mainstream languages and finds out that none would work.

Agda: Ergonomics + Correctness

He gives an example of a language that has this property, Agda. It's actually not a traditional language but a proof assistant. The way lookup is defined is the following way:

getify

"use strict";

[foo,bar] = TNG(foo,bar);
// NOTE: intentionally not TNG(..) wrapping useBaz(), so that it's
// basically like a "custom hook" that can be called only from other
// TNG-wrapped functions

function foo(origX,origY) {
   var [x,setX] = useState(origX);
   var [y,setY] = useState(origY);

Note:

When this guide is more complete, the plan is to move it into Prepack documentation.
For now I put it out as a gist to gather initial feedback.

A Gentle Introduction to Prepack (Part 1)

If you're building JavaScript apps, you might already be familiar with some tools that compile JavaScript code to equivalent JavaScript code:

• Babel lets you use newer JavaScript language features, and outputs equivalent code that targets older JavaScript engines.

import React from 'react';

function onlyChild(children) {
  return Array.isArray(children) ? children[0] : children;
}

export function combineContext(contexts) {
  class Provider extends React.Component {
    render() {
      const init = this.props.children;

// I'm suggesting we add a new "adopt X from <Y />" syntax to the JSX language
// it would de-sugar to render prop children, but look and read better than
// what we currently have. For example:

// 1.
// this sugar
function MyComponent(props) {
  adopt foo from <Bar />;
  return <div>{foo}</div>;
}

state-machine-component

A tiny (265 byte) utility to create state machine components using two pure functions.

🔥 JSFiddle Demo

Usage

The API is a single function that accepts 2 pure functions as arguments:

# Example config file /etc/vsftpd/vsftpd.conf
#
# The default compiled in settings are fairly paranoid. This sample file
# loosens things up a bit, to make the ftp daemon more usable.
# Please see vsftpd.conf.5 for all compiled in defaults.
#
# READ THIS: This example file is NOT an exhaustive list of vsftpd options.
# Please read the vsftpd.conf.5 manual page to get a full idea of vsftpd's
# capabilities.
