    async/await is just the do-notation of the Promise monad

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

  
## minimal.asm
org 0 ; We use "org 0" so Relative Virtual Addresses (RVAs) are easy.
      ; This means that when we want an absolute Virtual Address we have
      ; to add IMAGE_BASE to the RVA (or whatever the base of that section is)

IMAGE_BASE equ 0x400000
SECT_ALIGN equ 0x200
FILE_ALIGN equ 0x200

                Rust Val
              
          
    Make a Val with rust.

Build a https://www.val.town/ val with rust.
This is an example of how to compile a rust file to wasm and use it as a val.
Requires rust, wasm-pack and deno.
Usage


Put your code in val.rs.
Build it.

Mutate the original array


Add to original:

arr.push
arr.unshift

process.stdin.setRawMode(true)
process.stdin.resume()
process.stdin.setEncoding('utf8')

const server = http.createServer((req, res) => {
  res.statusCode = 200
  res.setHeader('Content-Type', 'text/html')
  res.write('<html>')

## lemonbar.sh

#!/usr/bin/bash

Cal() {
