"For any development task, there are a million ways to do it wrong, and the one correct way is a small, narrow trail that winds quietly through the forest. It takes experience to know the path and to avoid the dangerous pitfalls along the way. The following is a list of seven hard-won lessons from many trips into the dark forest. It is an opinionated look at what to do and what not do when navigating the treacherous trail of coding an application."
"Being American, my habit is to look left, so I appreciated the advice. But I couldn't shake the habit, so I ended up looking both ways. And I realized that looking both ways was a good metaphor for coding: Protect against the impossible, because it just might happen. Code has a way of surprising you, and it definitely changes. Right now you might think there is no way that a given integer variable would be less than zero,"
Software development contains many potential pitfalls, with only a narrow correct path requiring experience to navigate. Favor defensive coding by anticipating impossible states and guarding against unexpected inputs or future changes. Adopt a single-responsibility approach so each element performs one task to avoid cascading trouble. Use concrete, opinionated rules to minimize snags, missteps, and misadventures during application development. Practical, experience-driven lessons help maintain course and deliver reliable software with fewer surprises. Heed simple precautions to reduce errors and make code more robust against future developer changes and unforeseen conditions.
