APL (A Programming Language) is a high-level, domain-specific programming language known for its concise syntax and powerful array manipulation capabilities. Developed in the early 1960s by Kenneth E. Iverson, APL was initially created to assist in mathematical notation and to facilitate the representation and execution of algorithms in a more intuitive way. Its unique character set and notational approach allow users to express complex operations succinctly, making it particularly suited for mathematical, statistical, and scientific computations.
