    }

    public A(){
         Console.WriteLine("construct default A");
    }

    public void Method(){
         Console.WriteLine("called method of A");

    }

    public B(){
         Console.WriteLine("construct default B");
    }

    public void Method(){

Using Orderby ascending and Orderby descending to sort array javascript

Array.prototype.orderby=function()
{
  let self=this;
  let arr=[self[0]], i=1;
    for(;i<self.length; i++)
    {
      let index=arr.findIndex(f=>f > self[i]);
      arr.splice(index==-1?arr.length: index, 0, self[i]);
    }
  return arr;
}

Array.prototype.orderdescby=function()
{ 
 let self=this;
 let arr=[self[0]], i=1;
    for(;i<self.length; i++)
    {
        let index=arr.findIndex(f=>f < self[i]);
        arr.splice(index==-1?arr.length:index,0,self[i]);
    }
 return arr;
}

const points = [40, 100, 1, 500, 25, 107,0];
console.log(points.orderby())
console.log(points.orderdescby())
