Lodash gets so many things wrong I’d rather not see it in most projects. I appreciate a good utility library for JS projects but my go-to choice has to be Ramda[1]. Every function it exports is curried and works great with pipe which enables me to write highly reusable and composable functions in pointfree notation. I have never been as productive with lodash, and I find the functional style easier to read [1] https://ramdajs.com/ https://ramdajs.com/

Cannot recommend Ramda enough. It's a great utility belt to build your application with. Only downside is the pushback I always receive from the team when I try to introduce it.

  Reading the insightful comments in this post, I see why accommodating JavaScript's inherent flaws has snowballed web development. You need to know concepts like tree-shaking (removal of dead code) to pick among 10 different libraries that mostly do the same in subtly different ways.

What is "pipe"? Surely you're not referring to the bitwise-or operator `|`?

  Ramda has a composition (left to right) function named pipe: https://ramdajs.com/docs/#pipe https://ramdajs.com/docs/#pipe It's similar to the pipe operator seen in other languages (Elixir, F#, etc). There is a proposal to add a pipe operator to JS as well - still in early stages, though.

  It’s for connecting functions together like a pipeline, the same as compose but the fn list is reversed. Lodash has something similar called chain, but that’s harder to extend and isn’t as portable as partially applied functions

I've similarly enjoyed Remeda for first-class Typescript support, though I don't know it intimately and it is a much smaller project.

if you enjoy functional programming and are looking for a utility library, ramda has been a joy. very very well thought out. being able to compose functions together and treat data as a stream of information being transformed is incredibly easy. it is also compatible with libraries which implement algebraic structures like fantasy land. coupled with the other r libs its quite fun to program with. just be careful as it gets hairy to read pretty fast if one doesn't understand all the functions that come into play... // pull traits dictionary out of tokens const extractTraits = R.pipe( R.map(R.pipe( R.last, R.prop('attributes'))), R.reject(R.isNil), R.reduce(R.mergeWith(concatValues), {}), R.map(R.pipe( R.unless(R.is(Array), R.of), R.groupBy(R.identity), R.map(R.count(R.identity)), R.toPairs, R.sortBy(R.prop(0)), R.map(R.zipObj(['name', 'count'])))));

How does it compare with fp-ts?
