In this lesson we'll see how Ramda's path and pathOr functions can be used to safely access a deeply nested property from an object while avoiding the dreaded checks for undefined at each new property in the desired path. const R = require('ramda');…
Among the features introduced to the language of JavaScript in ES2019 is Array.prototype.flat. In this lesson we'll see just how easy the flat method makes the process of unboxing arrays regardless of how deeply nested they may be. Deep flatten: , ,…
Sometimes you just need a subset of an object. In this lesson, we'll cover how you can accomplish this using Ramda's pick and omit functions, as well as the pickAll and pickBy variants of pick. const R = require('ramda'); const {pick, prop, pickBy, p…
When doing comparisons inside of functions, you end of relying heavily on the argument passed into the function. Ramda's converge allows you to do comparisons in a Point-Free style allowing you more flexibility with composing and constructing functio…
You can really unlock the power of ramda (and functional programming in general) when you combine functions. Counting words in a string may seem like a relatively difficult task, but ramda makes it easy by providing a countBy function. This lesson wa…
