 The logic described above is somewhat classical. Now, let's bring in the "extra" features of JavaScript.

 For comparisons like `obj1 > obj2` or for a comparison against a primitive `obj == 5`, objects are converted to primitives. We'll study how object conversions work very soon, but to tell the truth, such comparisons are needed very rarely -- usually they appear as a result of a programming mistake.

 So, copying an object variable creates one more reference to the same object.

 - All lowercase letters go after uppercase letters because their codes are greater.
 - Some letters like `Ö` stand apart from the main alphabet. Here, it's code is greater than anything from `a` to `z`.

 The "right" algorithm to do string comparisons is more complex than it may seem, because alphabets are different for different languages.
