Let's begin by taking a look at some easy changes that can be made to our code.

Optimizing the three most obvious bottlenecks

Judging by the profiler's results, there is quite a bit of room for improvement of the code we've written so far. In this section, we're going to be addressing three of the most inefficient implementations and how they can be fixed.
