I have been trying to understand Javascript equality. Can you please tell me why the following line returns false?

alert((function a(){}) == (function a(){})) // false

But as you can see from the following cases < returns false but <= returns true, which means == should return true but it is false. Do you have any idea, WHY?

alert((function a(){}) < (function a(){})) // false
alert((function a(){}) > (function a(){})) // false
alert((function a(){}) <= (function a(){})) // true
alert((function a(){}) >= (function a(){})) // true

    You are comparing two object using < , <=, and they are actually compared with string they could covert to.

    "function a(){}" < "function a(){}" is false.

    "function a(){}" <= "function a(){}" is true.

    EDIT:
    Why (function a(){}) == (function a(){}) returns false is because you are compare same type with ==, so they don’t need to covert to string or number to compare, they are two different objects.
