In software engineering, rubber duck debugging (or rubberducking) is a method of debugging code by articulating a problem in spoken or written natural language.

Rubber duck debugging is a method used by programmers to debug code by explaining it, line by line, to an inanimate object, such as a rubber duck. The process of articulating the problem and explaining your code out loud often helps you identify the root cause of the issue.

The concept of rubber duck debugging is simple: you explain your code to a rubber duck (or any inanimate object, really) as if it were a fellow developer. The act of verbalizing your thought process and the logic behind your code can help you identify any errors or gaps in your understanding.

Rubberducking is the simple technique of explaining your code, or whatever you’re working on, to a rubber duck, and, in the process of explaining it, finding the answer yourself. Rubberduck debugging is a term in software development as the process of figuring out a solution to a bug or problem.

Rubber duck debugging is based on a technique called "active listening," which involves actively listening to someone else to fully understand their point of view. By using this technique to explain code to a rubber duck, the programmer can gain a better understanding of the problem and potentially identify the root cause of the issue.
