A rubber duck is a small, typically yellow-colored, toy duck made out of rubber or a similar material. It is often used as a bathtub toy for children, as it can float on water and be easily played with during bath time. The rubber duck has a simple and iconic design, usually featuring a smiling face, a round body, and a flat bottom to help it stay afloat.In addition to its role as a toy, the rubber duck has gained cultural significance and is sometimes used in various contexts beyond its intended purpose. For example, the term rubber duck debugging refers to a programming practice where a developer explains their code or problem to an inanimate object (like a rubber duck) in order to help clarify their thoughts and find solutions to coding issues. This process of explaining the code step by step often helps programmers identify mistakes or think through complex problems.
