Lodash FP usage retrospective Coding with J.S.

DRANK

My current project is completing its third year. From the start, we've been using aggressively the Lodash FP library through our whole JS & TS codebase, whether it's on the Back-End or Front-End. I recently performed a small analysis of our usage of the library to spot some weird usages that have slipped through code reviews and make a small retrospective about how this tool and functional programming are used in a mature production app.The results of the analysis were sometimes surprising as some of the sanctified FP tools show little usage on our side, while some lesser-known or more basic functions are widely popular. Let's dig in after a small digression about the lib itself.Lodash... FP?Lodash ( is a widely used library in the JavaScript ecosystem. It provides invaluable algorithmic tools that can save developers lines of code, time and bugs. Its less known sibling is Lodash/FP. As per the documentation, this build is providing "immutable auto-curried iteratee-first data-last met…
