javascript object creation patterns

objectCreation.js

Object.defineProperty(newObject,"name", {
  value: "Kwame",
  writable: false,
  enumerable: true,
  configurable: true
});

var defineProp = function (obj, key, value) {
  var config = {
    value: value,
    writable: true,
    enumerable: true,
    configurable: true
  };
  Object.defineProperties(obj, key, config);
}
//Constructor pattern
function Car( model, year, miles ) {
  this.model = model;
  this.year = year;
  this.miles = miles;
 
}
