comparison puzzle

[noddy]

Hopefully the garbled first version of this post has been cancelled
- if not I apologise for it
Here is what I should have said

I am returning a value from a php file to an ajax response handler.

The php file return string might contain the string "whatever"
When I check the response text I can see it is there and I can put it
into myVariable and confirm this with an alert.

However when I do the comparison,
(myVariable=="whatever") returns false.

If instead of "whatever" I code the php file to return "42"
and then check as before
(myVariable=="42") returns false
but
(myVariable==42) returns true

I would be grateful if someone could explain what is happening here.
There is obviously something that I have not grasped.

TIA

if you intend to always compare as a string why not use typing
myVariable.toString() == "42"

Thanks for that suggestion Matt
