Javascript OOP best practices? [closed]

Answer 1

I use such a pattern and recommend to you to use it too:

function Person(firstname, lastname, age)
{
  var self = this;
  var _ = {};

  // Private members.  
  var firstname  = firstname;
  var lastname = lastname;
  var age = age || 'unknown';

  // Private methods.
  function first_letter_to_uppercase(str) {
    return str.charAt(0).toUpperCase() + str.substr(1);
  }

  // Public members and methods.
  _.get_age = function()
  {
    return age;
  }

  _.get_name = function()
  {
    return first_letter_to_uppercase(firstname) + ' ' +
      first_letter_to_uppercase(lastname);
  }
  return _;
}

var p = new Person('vasya', 'pupkin', 23);
alert("It's "  + p.get_name() + ', he is ' + p.get_age() + ' years old.')
