Here is a piece of code that I actually copied from the documentation.
While coding a similar, the isNumeric function definition seems very
confusion to me.
Can anybody explain that?.
package {
import flash.display.Sprite;
public class Array_every extends Sprite {
public function Array_every() {
var arr1:Array = new Array(1, 2, 4);
var res1:Boolean = arr1.every(isNumeric);
trace("isNumeric:", res1); // true
var arr2:Array = new Array(1, 2, "ham");
var res2:Boolean = arr2.every(isNumeric);
trace("isNumeric:", res2); // false
}
private function isNumeric(element:*, index:int,
arr:Array):Boolean {
return (element is Number);
}
}
}
