JavaScript Objects II Notes

• Constructors are actually their own type of class
• A public method can return a private variable along with other private methods
• Use "var" in a class to make the variable private and "this" to make it public
•    this.age = age; (public)
     var bankBalance = 7500; (private)
• Inheritance is useful when 2 classes share similar properties
• "Child".prototype = new "Parent"()
• If you want a method to work with all the members of a class use "prototype"

• className.prototype.newMethod =
  
  function() {
  statements;
  };
  

• "Typeof" allows you to determine the type of a variable
• "hasOwnProperty" returns true or false whether or not an object has a certain property
• This is useful for if else statements
• "for in loops" are simplified for loops that look like this

• for (var properties in nyc){
      console.log(nyc[properties]);
  }

  • bracket notations can be used to print the values of an object
