Many years ago, I set my sights on becoming a senior developer. I achieved that goal! I wish I could say it was a matter of hard work and perseverance, but no, that wasn’t enough. JavaScript stood in my way, and it was while grappling with it that I came across one silly sentence in Marijn Habernecker’s classic book. You’re so excited that you aren’t sure where to begin, who to hire, or what to do next. You wish you had a trusted, who felt more like a friend that could take the guesswork.
