Even though Ramda is definitely more powerful, and I do prefer Ramda over lodash, I've found that for a lot of common operations lodash is simpler to use. Warning! @vvgomes lodashFP can easily be point free if you make a to uppercase function, the only difference is ramda has such a utility function built in. A utility library with a focus on flexible functional composition enabled by automatic currying and reversed argument order. Functions like that give Ramda a larger footprint, but also decrease the amount of code you need to write for common functions like that. https://jsperf.com/ramda-vs-lodash/3, However, both are extremely sluggish as compared to native imperative code. Ramda seems to be better in terms of speed: https://jsperf.com/ramda-vs-lodash This all seems cool but in the end what is the performance difference. Note: It is possible that some search terms could be used in multiple areas and that could skew some graphs. For instance, when you iterate object properties with lodash it will skip "hidden" properties (that start with _) by default. ukslim / ramda-typescript.md. Like range(30, 32) yields [30, 31, 32]. As a result this course isn't to convince you, today's JS developer, of how awesome FP is. Modules, Functional Programming, Util, Stdlib. Skip to content. In a language without static typing currying is just a pretty bad idea. @vvgomes lodash-fp comes with compose, too.
