You must identify and report problems as early as possible. Instead of letting issues quietly propagate through the system, you should break the flow and demand attention and repair. This keeps your codebase robust. It ensures that the real issue is addressed right away instead of discovering it far down the execution line when it’s buried in logs, far removed from the root cause.
Understand Modern Software
In the 1950s, computing errors were costly. The process of running code involved punch cards, compilers, and long waits between each stage. If your program failed, discovering the cause of the problem could take hours or days. Back then, fast feedback was crucial to avoid wasting precious machine time. Fast forward to today, the systems and processes have evolved and although good products have daily builds and releases,the need for early detection of issues is still a goal of clean and reliable code.
