Programming language theory is the branch of computer science that deals with the design, implementation, analysis, characterization and classification of programming languages. Its deepest root predates electronic computers: the lambda calculus, developed by Alonzo Church and Stephen Cole Kleene in the 1930s, is considered by some to be the world's first programming language, and it still anchors how the field reasons about computation and meaning.

Origin YearThe lambda calculus, developed by Alonzo Church and Stephen Cole Kleene in the 1930s, is considered by some to be the world's first programming language and the field's mathematical root; Noam Chomsky's 1956 work on formal grammars is a second, later origin point some scholars use instead. Core ConcernWhat programming languages can express, how they are given precise meaning, and how they are designed and implemented. 1 Programming Language Theory
