The ~ (tilde) can have different meanings: it can be an operator, performing a bitwise negation on a binary number - all 1 bits are set to 0 and all 0 bits are set to 1. It can also simply be the tilde character itself, as used in Windows for shortening long path names.

How does the ~[] construction work in JavaScript?
I've come across a working JavaScript code that I can't explain.
For example:
+[]===0
-[]===0
~[]===-1
~-~[]===-2
~-~-~-~-~[]===-5
~-~-~-~-~[]+~[]===-6
~+~[]===0
~+~+~[]===-1
~+~+~+~[]===0
Can you explain the logic of these expressions?
