"To create a new member function, create a new anonymous function and assign it to the prototype property of the object. "

I prefer not to use anonymous function. I will use named function so that my stack trace is comprehensible when I am debugging.

  myObject.prototype.memberMethod = function()
  {
    // code to execute within this method
  }

becomes

  myObject.prototype.memberMethod = function memberMethod()
  {
    // code to execute within this method
  }
 

Also, what's up with naming the constructor function as 'myObject'. JS prototypical nature is confusing as is and using an example like this can only make it harder to understand.
