this.name= name;
this.uppercase= function (){

You are trying to convert to the entire object to upper case, if you check the console it tells you that the element has no method toUpperCase. Instead convert the string, not the object.

return this.name.toUpperCase();

You need to do

function mystring (name,uppercase){
    this.name= name;
    this.uppercase= function (){
        return this.name.toUpperCase();
    };

}
var jj= new mystring('mycompany');
jj=jj.uppercase();
console.log(jj);

You forgot the this.name in the this.uppercase function
