let map = new Map();
map.set("a", 1);
map.set("b", 2);
map.set("c", 3);

let obj = [...map.entries()]  // or Array.from(map) - either works;
    .reduce((acc, [key, value]) =>
      ({ ...acc, [key]: value }),  // Can also spread in reduce or assign, latter is quicker but I love spread syntax lol

How to make a Minecraft mod

Minecraft mods, especially mods which change the client, are by and large written with Forge. If you visit their website, you'll be greeted abruptly by a mysterious message at the top of an SMF forum, with no clear path towards actually... making a mod. I'm documenting here the steps I went through to get started, in the hopes of helping the next person have an easier time of it.

I'll be using Scala for this guide, but it should be fairly easy to adapt these instructions to any JVM language (e.g. clojure or if you're feeling masochistic, Java). I'm also developing on OS X, so some of the commands will be a little different if you're on Linux or Windows. I'm assuming you have some proficiency with your operating system, so I won't go into details about how to adapt those commands to your system.

Background

Minecraft doesn't have an official mod API (despite early [promises](http://notch.t

// replace "user-id" with your actual user id e.g. "123455" & same for auth url
const userId = 'my-user-id-goes-here';
const authUrl = 'auth-url-goes-here';

// first gather up all the DOM nodes in the list that have anchors w/ the title id to delete
const nodes = document.querySelectorAll('.rowList .title > a');

[12:03 AM] acemarke: "controlled" and "uncontrolled" inputs
[12:04 AM] acemarke: if I have a plain, normal HTML page, and I put <input id="myTextbox" type="text" /> in my page(edited)
[12:04 AM] acemarke: and I start typing into that textbox
[12:04 AM] acemarke: it remembers what I've typed. The browser stores the current value for that input
[12:05 AM] acemarke: and then sometime later, I can get the actual element, say, const input = document.getElementById("myTextbox"), and I can ask it for its value: const currentText = input.value;
[12:05 AM] acemarke: good so far?
[12:08 AM] acemarke: I'll keep going, and let me know if you have questions
[12:08 AM] lozio: ok, actually I'm reading
[12:09 AM] lozio: good
[12:09 AM] acemarke: so, a normal HTML input field effectively stores its own value at all times, and you can get the element and ask for its value
