JS gets even weirder when you include all the comparison operators.

Did you know undefined is equal to undefined, but not <= undefined or >= undefined?

Or that two instances of the same object/array are not equal (e.g. [-1] != [-1]), but are both <= and >= each other?

Or that /.*/ is non-comparable (only != is true) to all numbers, but greater than [-0.5] and "-0.5", and less than [0] and "0"?

Most of the examples you point out make sense if you know that using greater than or less than casts the value to a number. >= and <= always cast their parameters to numbers while == only does if either side is already a number.

If you define "make sense" as "having an explanation not rooted in the supernatural", then yes.

By that definition, Brainf*ck[1] also makes sense.

What a clusterfuck.

And yet, people say Brendan Eich doesn't believe in equality!
