Script Preparation code:



pr=function(){
    let a=0;
    this.add=()=>{
       a+=1;
    }
};

const pro={
   a:0,
   add(){
     const $=this;
       $.a+=1;
  }
};

const pro2=Object.assign({},pro);
pro2.add2=function(){
	const $=this;
    $.a+=1;
};


class Pr {
    constructor() {
        this.a = 0;
    }
    add() {
        this.a += 1;
    }
}

let c=0;

Tests:

function
k = new pr(); for(c=0;c<1000;c++){ k.add(); }
object
const ob=Object.assign({},pro); for(c=0;c<1000;c++){ ob.add(); }
object with extern method
const ob2=Object.assign({},pro2); for(c=0;c<1000;c++){ ob2.add2(); }
class
j=new Pr(); for(c=0;c<1000;c++){ j.add(); }
