In computer science, an expression is a syntactic entity in a programming
language that may be evaluated to determine its value. It is a combination
of one or more constants, variables, functions, and operators that the
programming language interprets (according to its particular rules of
precedence and of association) and computes to produce ("to return", in a
stateful environment) another value. This process, for mathematical expressions,
is called evaluation.
In simple settings, the resulting value is usually one of various primitive
types, such as numerical, string, boolean, complex data type or other types.
Expression is often contrasted with statement—a syntactic entity that has no
value (an instruction).
