Can you convert a Value Object (i.e. JSON) to YAML?

My Expectation

My expectation is that a mid-senior level developer should be able to accomplish this task in under 4 hours:

• write a basic solution in 30-60 minutes
• debug / test / fine-tune for another 60-90 minutes
• document, package, and publish within the remaining time

I could see it reasonable even if a developer takes 2 days to solve this for the first time - possibly because they needed to take a break but didn't, such as feeling pressure and getting brain freeze, taking an initial wrong approach, over-thinking the problem, and then just keeping beating the dead horse, etc - especially if they've never had to work independently before.

The Developer Litmus Test

I used to think that fizzbuzz was a stupid way to test if someone is a developer.

Now I think that it's a good litmus test.

However, I think I've found a better one...

    const model = %yourSequelizeModel%
    for (let assoc of Object.keys(model.associations)) {
      for (let accessor of Object.keys(model.associations[assoc].accessors)) {
        console.log(model.name + '.' + model.associations[assoc].accessors[accessor]+'()');
      }
    }

require('crypto').randomBytes(48, function(err, buffer) { var token = buffer.toString('hex'); console.log(token); });

var debug = process.env.NODE_ENV !== "production";
var webpack = require('webpack');

module.exports = {
  context: __dirname,
  devtool: debug ? "inline-sourcemap" : null,
  entry: "./js/scripts.js",
  output: {
    path: __dirname + "/js",
    filename: "scripts.min.js"

Now published as @root/uuid

• Node version: https://github.com/therootcompany/uuid.js/blob/main/uuid.js
• Browser version: https://github.com/therootcompany/uuid.js/blob/main/browser.js

This is started out as a curiosity, pasted as a gist but now, years later, I've come back to it because there are too many of these uuid modules out there and they're too complicated.

This, however, is easy to read and understand (for me, at least). Even its tests are dependncy and build-step free.

This is the follow up to a post I wrote recently called From Require.js to Webpack - Party 1 (the why) which was published in my personal blog.

In that post I talked about 3 main reasons for moving from require.js to webpack:

1. Common JS support
2. NPM support
3. a healthy loader/plugin ecosystem.

Here I'll instead talk about some of the technical challenges that we faced during the migration. Despite the clear benefits in developer experience (DX) the setup was fairly difficult and I'd like to cover some of the challanges we faced to make the transition a bit easier.
