Why is isNaN(null) == false in JS?

Question

This code in JS gives me a popup saying \"i think null is a number\", which I find slightly disturbing. What am I missing?

Answer 1

Note:

"1" == 1 // true
"1" === 1 // false

The == operator does type-conversion, while === does not.

Douglas Crockford's website, a Yahoo! JavaScript evangelist, is a great resource for stuff like this.
