👉 The term "nondurably" is a term used in computer science and programming to describe a data structure that allows efficient manipulation of memory without explicitly maintaining references to the underlying data. This means that when the data structure is modified, it does not require any changes to its backing storage, making it faster and more efficient than traditional methods. Nondurably structures are often used in applications where memory management is important, such as databases, file systems, or communication networks. By using nondur
