Prevent Common Go Bugs with Custom Types

In Go development, mixing up integers, strings, or UUIDs representing different things leads to subtle bugs. This post introduces a simple yet effective technique: define distinct types for different meanings. For instance, use AccountID and UserID for account and user IDs respectively; the compiler will catch type mismatches, preventing errors. The author demonstrates this in their libwx weather library, avoiding errors from using generic types like float64. This simple yet often overlooked technique is worth adopting.
