Because string length is not a function, it's a property.

 function extractMiddle(str) {



        var position;

        var length;



        if(str.length % 2 == 1) {

            position = str.length / 2;

            length = 1;

        } else {

            position = str.length / 2 - 1;

            length = 2;

        }



        return str.substring(position, position + length)

    }



    console.log(extractMiddle(handbananna));
