When introducing "Comparison", maybe we can also cover coercion, and the important difference between == and ===?

[tvooo]

Before going into == vs === we'd also have to have introduced the concept of references vs. values. Just to keep that in mind.

Codepen does not have a "run" button, so it's quite intransparent when it actually re-runs a program. Maybe a different tool is better? A simple jsbin configuration, maybe?

@tvooo CodePen does have a "run" button. You can disable Auto-Run by going to Settings -> Behaviour -> Disable "Auto Updating Preview".

Regarding == vs ===, I agree it can a lot broader topic, but I was hinting at merely introducing the difference between the two, and why we recommend they write ===, as that will probably be the main comparison operator they'll be using with the beginner topics. We don't even have to cover object comparison (as I'm guessing that's where your concern was), we can just quickly talk about "coercion" (maybe not mention that term to avoid confusion), and just mention that "2" == 2 is true and "2" === 2 is false.

I would like to hear other people's opinion on this, but I thought we could include "references" vs. "values" in the second lesson, when we go more in depth into objects, as in this first lesson we're just introducing them?

Awesome, that's good to know.

Maybe it is worth going into coercion in the first lesson after all. Let's see how our exercises turn out, and the rest of the lesson, and then we can always move it around.

@kabaros I'm pretty busy the rest of the week and won't be able to work on this before the weekend, but I have blocked a couple of hours on Saturday. Hope that's alright.

@tvooo I've merged the PR for lesson 1. The topics are perfect - it's what needs to be covered - but I think it will have to be shifted between the lessons as it would be too much for the first one.

The levels of details sounds reasonable, especially for the first lesson. But as a general rule, it would be good to have as less as possible on the lesson itself and then add pointers to (good) documentation like MDN or such

This just came in from the Mozilla newsletter. I think it's great to point to in between topics and exercises: https://developer.mozilla.org/en-US/docs/Learn/Getting_started_with_the_web/JavaScript_basics
