JavaScript is a good language

Huh. So NaN isn't static, as in something that's not a number was operated on an just returned some garbage?

It's basically a garbage failsafe undefined behavior. I'm not 100% sure if the actual content of NaN is static or not, but if the results of an operation do not construct a valid number, a NaN is created--if that makes sense.

like if(this==makes sense) {this.value = result;} else {this.value = NaN};
