Listof

Listof is not a single, widely defined term or standard; rather, it functions as a concatenation of the words “list” and “of” that appears in programming, documentation, and data modeling to denote a collection of items. In software development, the lowercase form listOf and the capitalized form List.of appear as standard library facilities for creating lists.

In Java, List.of(...) is a static factory method introduced in Java 9 that returns an immutable List containing the given elements. In Kotlin, listOf(...) is a top‑level function that returns a read‑only List<T>, with mutable variants such as mutableListOf provided as alternatives. Other languages and APIs employ similar naming patterns (for example, Array.of in JavaScript creates an array), illustrating a common convention to express a list‑constructed value.

Beyond concrete functions, the phrase “List of T” is widely used in type notation and API design to describe a collection containing elements of type T. Some design communities adopt a naming convention such as ListOf<T> to reflect this idea in types or helper functions, though exact syntax varies by language.

In documentation and encyclopedic writing, many pages use the title format “List of X” to present enumerations. Style guides differ on capitalization and punctuation, but the underlying goal is consistency and clarity in presenting a list-based topic.

Overall, Listof serves primarily as a linguistic and naming cue rather than a single, universal library or standard, with concrete meaning tied to the specific language or domain in which it appears.
