Explore the fundamentals of F#, a functional-first programming language, in this comprehensive conference talk. Discover how F# enables developers to write simple code for complex problems through key features like curried functions, partial function application, record types, discriminated unions, pattern matching, units of measure, type providers, and computation expressions. Learn about the advantages of the functional-first paradigm, understand the language's rich type system, and see practical examples including Reverse Polish Notation implementation. Gain insights into F#'s powerful capabilities, from CLI mutability and tuple handling to abstract syntax trees and active patterns, all designed to enhance code simplicity and problem-solving efficiency.
