Javscript Creational Pattern

creational.js

/*
 * Creating new Objects
 * https://developer.mozilla.org/pl/docs/Web/JavaScript/Guide/Working_with_Objects
 */
let myObj = new Object();
let myObj = {}; // preffered method
let myObj = Object.create(Prototype, {name: 'Foo'});

/**
 * Adding properties
 */

// Preferred method
myObj.property1 = 'foo';

// Allows to use special characters in property names (e.g. '-')
myObj['property2'] = 'bar';

// Allows to specify additional information about property
// such as enumerable, configurable, writable
// https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/defineProperty
Object.defineProperty(myObj, 'property3', {
  value: 'baz',
  enumerable: true
});

// Similar to defineProperty, but allows to define multiple properties
// https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/defineProperties
Object.defineProperties(myObj, {
  'property4': {
    value: 'foo',
    writable: true
  }
});
