Benchmark: public vs closure vs private

Script Preparation code:

class PropertyAccess {
  _public = 0;
  #private = 0;
  
  constructor() {
    let closure = 0;
    this.closure_update = function() { closure++; };
  }

  public_update(){ this._public++; }
  private_update(){ this.#private++; }
}

window.__measurethat_property_access = new PropertyAccess();
console.log(__measurethat_property_access);

Tests:

public
const pa = __measurethat_property_access; for (let x = 0; x < 1000; x++) pa.public_update();
closure
const pa = __measurethat_property_access; for (let x = 0; x < 1000; x++) pa.closure_update();
private
const pa = __measurethat_property_access; for (let x = 0; x < 1000; x++) pa.private_update();
