I WONDER - What Does Debugging Mean?

Debugging is the process of identifying and removing errors, known as bugs, from code to prevent unexpected behavior or crashes. The debugging cycle involves identifying, isolating, and fixing problems, followed by testing to ensure all bugs are resolved. Debugging is essential as coding mistakes are common and bugs are hard to avoid. While most debugging is reactive, preemptive debugging can prevent issues before they occur.
