Benchmark: Data Properties vs. Accessor Properties vs. Getter / Setter Methods v2

Data Properties vs. Accessor Properties vs. Getter / Setter Methods v2 (version: 0)

The purpose of this benchmark is to determine the performance differences between data properties, accessor properties and getters / setter functions.

Comparing performance of: Read from data property vs Write to data property vs Read from accessor method vs Write to mutator method vs Read from object literal property vs Write to object literal property vs Read from object literal property on prototype vs Write to object literal property on prototype

Script Preparation code:

const foo = 5


const data = {
  property: foo
};



cindt method = {
  getProperty: function() {
    return foo;
  },

  setProperty: function(value) {
    property = value;
  }
};

const objectLiteralAccessor = {
  get property() {
    return foo;
  },
  set property(value) {
    property = value;
  }
};

function Class() {
}

Class.prototype = {
  get property() {
    return foo;
  },
  set property(value) {
    property = value;
  }
};
    
var prototypeAccessor = new Class();

Tests:

Read from data property
var value = data.property;
Write to data property
data.property = true;
Read from accessor method
var value = method.getProperty();
Write to mutator method
method.setProperty(true);
Read from object literal property
var value = objectLiteralAccessor.property;
Write to object literal property
objectLiteralAccessor.property = true;
Read from object literal property on prototype
var value = prototypeAccessor.property;
Write to object literal property on prototype
prototypeAccessor.property = true;
