Of course, lodash has curry too, but it is not turned on for its own functions.. 2 - Ramda includes several functions missing from lodash (but are part of the separate lodash-contrib library). You signed in with another tab or window. With pipe applying those properties is a bit more complicated as those properties aren't clear. Warning! To illustrate the size difference in numbers - my custom Ramda build was 24.6 kB, while the same methods in Rambda take only 7.6 kB. I mean when you end up working on the project where half of devs love Ramda and the other half worship Lodash the only reasonable argument is performance. I'm going to move that out here. Plus, "flow" doesn't map well to the function composition if compared to Ramda's "compose". A utility library with a focus on flexible functional composition enabled by automatic currying and reversed argument order. Note: It is possible that some search terms could be used in multiple areas and that could skew some graphs. This all seems cool but in the end what is the performance difference. Ramda seems to be better in terms of speed: https://jsperf.com/ramda-vs-lodash @vvgomes lodash-fp comes with compose, too. Hopefully that will change in the future.

Compare Ramda and lodash's popularity and activity. @qiansen1386 the reason compose is the reverse of pipe is because it is the mathematical concept of function composition. ), And if we strip @a-x- version of unnecessary underscores… ;-), Someone would have to try extra hard to convince me that 9 function invocations of 9 different Ramda methods (all of which you along with all present and future team members have to have memorised) is better in any aspect…, @kamiltrebunia what if companies or c.name is null or undefined? The point is not being shorter. They are equivalent - func. Promoted. pluckStateEnum is equivalent to R.prop('enum') ordersByState can have the nesting level reduced, additionally, checking if the intersection of two arrays is empty can be better represented with R.any(R.contains(R.__, arr1), arr2). ramda has a bigger community of maintainers.
