How does -Infinity work?
STACKOVERFLOW = [];
turkeycheck = Math.max.apply(null, STACKOVERFLOW);
if(!turkeycheck){
// See Below
}
console.log(turkeycheck);
console.log(turkeycheck.length);
Also can be seen here: http://jsfiddle.net/L4zgfcmz/5/
Curious why it (!turkey)
doesn't get hit, but using turkeycheck.length
shows it undefined? If it's undefined doesn't mean it's false?
Also, if it turkey
is console logging -Infinity
, shouldn't the length turkeycheck
become 11?
I'm just confused as to why the parameter turkey
is set to -Infinity, but then it becomes undefined
.

-Infinity
- numeric value. Numeric values have no property .length
, so trying to read from it will return undefined
. The value stored in your variable turkeycheck
remains unchanged, and if you try to write its value after trying to register its length, you will still be shown the value -Infinity
.
var n = 1;
console.log(n.length); // undefined
console.log(n); // 1
