I found out that in JavaScript [[[!![]+[]]+[]]+[]][+[]][+[]] evaluate to "t". How is it possible?
I do know that !![] evaluates to true, however how to you obtain "t" from that?
console.log([[[!![]+[]]+[]]+[]][+[]][+[]]);

Some ASCII weirdness. For example, this `[[[![]+[]]+[]]+[]][-[]][-[]]` evaluates to `f`. – Catalin Iancu Sep 14 '17 at 13:49

5`[[[!![]+[]]+[]]+[]]` evaluates to `["true"]` and `+[]` evaluates to `0` so `["true"][0][0]` evaluates to `"t"` – n00dl3 Sep 14 '17 at 13:52

How do you get `["true"]` from `[[[!![]+[]]+[]]+[]]`? Isn't `!![]` a boolean? – Sep 14 '17 at 13:54

1@User12345 `!![]` is `true`. `true + []` is `"true"`. That's how you get `["true"]`. – Marcos Sep 14 '17 at 14:04
