一、undefined

    1、In computer programming and mathematics, the term "undefined" holds significant importance. On the other hand, the undefined concept can also be intentionally leveraged to signal specific situations.

    2、 For instance, programmers might deliberately leave variables undefined to denote a condition where the outcome, result, or value is not yet determined, and appropriate action can be produced when encountering such a state. It's a state or condition indicative of a variable that has been declared but not assigned a value, an expression using a variable that is not well-defined in a particular context, or an operation that doesn't have a designated outcome. Despite seeming deceptively simple, understanding and properly handling "undefined" states are pivotal to producing clean, efficient, and reliable code, and to maintaining solid mathematical proofs and calculations. It's the embodiment of a key conceptual tool that gives rise to possibilities of expressing, manipulating, and comprehending the abstract nature of computational logic and mathematics.

    3、 Even more, in Javascript, "undefined" is a primitive type itself, uniquely signifying the absence of a defined value. Contending with undefined terms can pose challenges, as efforts to perform operations on them often lead to errors or unstable outcomes.
