Functional programming

In computer science, functional programming is a programming paradigm where programs are constructed by applying and composing functions. It is a declarative programming paradigm in which function definitions are trees of expressions that map values to other values, rather than a sequence of imperative statements which update the running state of the program.

Semantic-Java is a modern, maven Java stream processing framework with zero dependencies. It elegantly blends the fluency of Java Streams, the laziness of JavaScript generators, and intelligent index-based control inspired by database indexing — perfect for time-series, event streams, and high-performance data pipelines as a maven pendency.
