How can two javascript objects be equal and not equal at the same time?

Question

Below is an example comparing two JavaScript objects but I am confused by the returned values.

var i=new Object()
var j=new Object()

i==j false

i!=j true

i>=j true

i<=j true

i>j false

i<j false

How are the values determined for the above? I am having trouble understanding.

Answer 1

Here are the reasons,

i==j false //Since both are referring two different objects

i!=j True  //Since both are referring two different objects

i>=j true  //For this, the both objects will be converted to primitive first,
           //so i.ToPrimitive() >= j.ToPrimitive() which will be 
           //evaluated to "[object Object]" >= "[object Object]" 
           //That is why result here is true.

i<=j true  //Similar to >= case

i>j false  //Similar to >= case

i<j false  //Similar to >= case

i<-j false //similar to >= case but before comparing "[object object]" will be negated 
           //and will become NaN. Comparing anything with NaN will be false 
           //as per the abstract equality comparison algorithm 

You mentioned i<-j will be evaluated to true. But that is wrong, it will be evaluated to false. See the reasons above.
