Revision 5 of this benchmark created on

Description

Evaluate difference adding external functions as methods to object instances or the prototype.

Setup

function test1() {
	return "test1: " + this.name;
}

function test2() {
	return "test2: " + this.name;
}

function test3() {
	return "test3: " + this.name;
}

Prototype Methods
class MyClass {
	constructor() {
		this.name = "proto";
	}
}
MyClass.prototype.test1 = test1;
MyClass.prototype.test2 = test2;
MyClass.prototype.test3 = test3;

const mc = new MyClass();
mc.test1();
mc.test2();

Instance Methods
class MyClass {
	constructor() {
		this.name = "instance";
		this.test1 = test1.bind(this);
		this.test2 = test2.bind(this);
		this.test3 = test3.bind(this);

Methods in class definition
