mapputxa1b2

Mapputxa1b2 is a symbolic identifier used in data modeling and programming pedagogy to illustrate the operation of inserting a key-value pair into an associative map. It commonly appears in tutorials, documentation examples, and mock APIs where a concrete function name is chosen for clarity.

Origin and construction: The name combines mapput, a conventional shorthand for “insert into a map,” with the suffix xa1b2, which in instructional contexts serves to distinguish a particular variant or example. The suffix does not reflect a formal standard; it functions as a tagging device within an educational text.

Conceptual behavior: In theoretical pseudocode, mapputxa1b2 is presented as a function that accepts a map, a key, and a value, and returns a new map containing the existing entries plus the new binding. This framing is often used to illustrate immutability, referential transparency, and the idea of creating updated versions of a data structure rather than mutating it in place.

Typical usage: A standard demonstration sequence might start with an empty map, apply mapputxa1b2 to insert a key such as "apple" with a value like 3, producing a new map, and then chain additional mapputxa1b2 calls to build up more associations. The example emphasizes predictable copy-on-write semantics and the composability of map operations.
