Thinking JavaScript 💡

The question posed to me was this :
Why does this first line "work" (compiles/runs) but the second line gives an error ⁉️

[[]][0]++;

[]++;


Not that I expect you'll ever intentionally write (or read, hopefully!) code like this, but being able to think more like JavaScript does always help you write better code. ✅

In this topic, we're gonna answer this question.
