hash — to produce a deterministic or consistent scalar value from an object for the purpose of fast storage and retrieval in a hash array for unordered linear collections like dict and bag. ideally, a hash is often a psuedo random number produced by seeding a random number generator with numeric data intrinsic to the object in question.   perl: the perl %hash type is a dict, in codish parlance.   python: hash(object) -> integer Return a hash value for the object.

assign — a statement that sets an lvalue to a value.   mentioned: destructure ✍

attr — an attribute of an object.   a setable and getable value associated with a symbol or name in an object.   in some languages, attributes are either private, protected, or public.   distinct: item   python: property   c++: member   aka: member, property   related: pair ✍

axis — a line that passes through an origin, passes through every value in one dimension, and is orthogonal with all others.   mentioned: atan, atan2, cardinal, plot ✍

back — pertains to the previous value.   opposite: forward   related: prev   opposite: fore ✍
