Until ECMA6, JavaScript had no classes. It had (and still has) prototypes.
A class is like a mold from which you build an object. A prototype is itself an object.

// think of this as the class AND its constructor
var Person = function() {
  this.canTalk = true;
};

// this is a 'class method'

  
## con1.js
// connectivity: ITERATION 1
var database = new Database('companydb');
database.connect(function(db) {
    if (db.error) {
        // handle error
    }
    // continue db ops
});
