HI! Meet pepka - JavaScript/TypeScript functional programming utility library named after my parakeet.
This lib is intended to be a functional toolkit more flexible than ramda is. Its' basic API is similimar to ramda's one. Other goals are:
- Async pipes. They are very handy, but are not 100% pure in terms of Haskell c:
- Most flexible types possible (Let'em be any better than crashing because of their failures. I'm currently working on full JSDocs and better basic types).
- Tree-shakeble and smallest possible. What could be native, is native.
- Has "quick" alternatives of most computation-heavy functions with
qprefix which are not completely safe by fp means: most of them do mutations and it may be needed tocloneorcloneShallowdata in a first pipe ofcompose(...). - Has basic toolbelt-types like AnyObject and AnyFunc<ReturnType?, [...args]?> etc.
- Has some basic additinal must-have stuff that ramda does not.
Full docs are coming, please reference ramda's ones for most operations and examples: https://ramdajs.com/docs/
Basic API differences:
- clone() clones deeply as possible any type possible.
- cloneShallow() clones only by 1st level of folding also any type possible.
- mergeDeep - replaces arrays.
- mergeDeepX - replaces its' elements with same indexes.
- mergeDeepAdd - adds new elements to arrays.
- type - returns type UpperCased of anything passed to it, including classes and typed arrays.
- mapKeys - changes existing keys and data by map or function like usual mapper.
- explore(label)(data) -
compose(explore('the number'))(42)results in'the number', 42in console passing by the data. - genBy(generator(index), length) - generates arrays.
- sizeof(array or object) - counts indexes of it.
- Aliases: mirror, reflect, echo = identity.
- Quicks: qappend, qassoc, qreduce, qmergeDeep, qmergeDeepX, qmergeDeepAdd, qmapKeys, qfilter
Async APIs:
- composeAsync - waits for a Promise if emitted by a pipe inside it.
- waitAll = Promise.all
- forEachAsync - runs a handler with all elements passed in parallel.
- forEachSerial - waits for a previous handler to resolve if Promise emitted.
