Good naming in code cuts down the mental work needed to understand and debug programs. Strong identifiers act like compression: they let you pack more meaning into each line. Studies show clearer names can slash debugging time by nearly 20%, and AI tools also gain the most from improved identifiers. When you call functions, design names that read like sentences—notify_all(registered_clients, about=the_new_version) carries more context than notify(…) alone. One trick is wishful thinking: sketch out calls as if every function existed, then build your code around those ideal names. That keeps your code readable without turning it into prose. Another tip is to replace primitive types with domain-specific ones. Swap int languageId for Language preferredRssFeedLanguage, and you free parameter names to explain why they’re there, not just what they are. Scope drives name length too—one-letter names fit tight loops, but public APIs demand full words. Drop prefixes that add noise. You don’t need IChatConnection—just ChatConnection says enough. Ditch get and set on methods. Instead of get_customer(id) and set_customer_status(...), write customer_for(customer_id) or suspend(a_customer). And steer clear of catch-all classes like Utils or Misc; they attract sloppy code. Each name shapes how you and others think about your design. Keep them precise, and you’ll save time now and later.
