 > x == x
=> true

still good...

 > x==!x
=> true

still goo.. Wait what?

x is equals x...

... but also different

 > 0.5+0.7==1.2
=> true

you nailed it!

 > 0.1+0.2==0.3
=> false

wait a minute...

... and even JS doesn't get it

 > true-true===0 
=> true

and it's consistent! I think true is === 1 right?

 > true===1
=> false

Doh!

 > typeof null
=> 'object'

> typeof NaN
=> 'number'

when null is not actually null

NaN (not a number) is in fact a number

NaN with an identity crisis

> NaN===NaN
=> false

true != true

> 'true'==true
=> false

round it up!
