Explore functional programming concepts and their application in Go during this GopherCon 2020 talk. Discover the benefits of functional programming and learn how to implement closures, currying, tail-recursion, and other techniques to solve real-world problems. Compare functional approaches to traditional methods, and gain insights into useful libraries that streamline functional Go programming. Delve into topics such as immutable functions, pure functions, side effects, idempotence, first-class and higher-order functions, and recursion. Examine practical use cases, including reducing function parameters and implementing server options. Investigate declarative programming, code generation, and potential drawbacks of functional programming in Go.
