Not my job title — they had that — but what <em>functional programming</em> is. I started in on the usual mumble about pure functions and immutability, watched their eyes begin the slow slide toward the exit, and then they rescued both of us with a guess:</p> <p>&ldquo;Functional programming&hellip; does that mean you write the code yourself, instead of having Claude do it? Is that the thing?&rdquo;</p>
