either love it or you hate it.</p> <p>But, like everything in software engineering, it is a trade-off.</p> <p>So for today, let&rsquo;s focus on the good, the bad, and the ugly parts of functional

it would be that I love what functional programming brings me.</p> <p>It reduces complexity, the code is nice and explicit, and it eliminates certain bugs from occurring.</p> <p>But there are a few things that I wanted to discuss regarding functional programming.</p> <h2 id="h2-0-object-orientation-vs-functional-programming">Object Orientation vs. Functional Programming</h2> <p>Let me start off
