Learning Functional Programming in Go

A time of reckoning

Why would we want to use pure FP in Go? If writing expressive, easy-to-maintain, and insightful code is more important than performance, then perhaps.

What are our alternatives? Later, we'll look at some pure FP libraries that have done the heavy lifting for us and have made strides toward being more performant.

Is that all there is to functional programming in Go? No. Not by a long shot. What we can do with FP in Go is currently partially limited by the fact that the Go compiler currently does not support TCO; However, that may change soon. For details see the How to Propose Changes To Go section in the Appendix.

There is another aspect to functional programming that Go fully supports: function literals. And as it turns ...
