Few weeks ago I published a practical Intro to Monads in JavaScript where I covered basics of Identity and Maybe monads. Some time later I added a tutorial on Either monad and fails-fast error handling. This time I will show you error accumulation in a simple Validation use case.
My simple and practical Intro to Monads in JS, where I covered basics of Identity and Maybe monads, seemed to be helpful for a lot of folks, so I’ve decide to continue the topic. Now it’s time for Either – a tool for fast-failing, synchronous computation chains. A tool that may increase readability and quality of code while reducing error proneness. The best part is that we can still ignore the category theory!
Can unfamiliar pattern from world of statically typed functional languages improve JavaScript world? For sure YES! The elastic nature of JavaScript can handle great ideas from many alien worlds. With a little help of modern tools like monet.js and TypeScript we can achieve awesomely descriptive aesthetics of our code and drop some imperative bloat.
If you’ve heard about Monads but never had time learn them, here’s a simple explanation. Not a theoretical nonsense. It’s a simple, practical tutorial for JavaScript developers showing how some monads can be used. It’s for engineers, not scientists.
Recently, our whole backend team visited Lambda Days - The Functional Programming Conference. Two days, multiple presentation tracks, lobby and pub talks gave our five agents unique glimpse into the state of the functional programming ecosystem.
