#3Great article. I've seen articles about this concept before, but none of these had such a thorough explanation!

It’s great my guy! Love the recap at the end

#5Is there a limit to what one can do with these six characters? Like, now we're reading values from the string "false". We also could read from "true", and maybe undefined (how?). But can one do more? If one can generate "window", one should be able to call functions through window["functionName"]() and do general computing with this, I think?

#6Pretty good explanation.
For those who want to dive deeper, there is an esoteric language based on these concepts: http://www.jsfuck.com/

#7you can make the final code slightly shorter by obtaining the "e" from "true" instead of "false". `(!![]+[])[+!+[]+!+[]+!+[]]`

you can obtain undefined by accessing the first element of an empty array. `([])[+!![]]`

As I understand, there's no limit to what you can do with these six characters.
It quickly gets more complicated though, and will require alot more code:
"undefined": [][![]]+[] (empty array accessed at index 0 turned into string)
"NaN": +{}
"[object Object][object Object]": {}+{}
.. etc
