F# is a strongly-typed functional programming language designed to empower programmers and domain experts to write simple, robust code to solve complex problems. It combines the succinctness, expressivity, efficiency, and compositionality of typed functional programming with the runtime support, libraries, interoperability, tools, and object models of modern programming frameworks. The aim of this book is to help you become an expert in using F# for a range of practical programming problems. Functional programming has long inspired researchers, students, and programmers alike with its simplicity and expressive power. Applied functional programming is booming: a new generation of typed functional languages is.
