Port some of the LoDash functions

Open Xion opened this issue 9 years ago • 0 comments

LoDash/Underscore is a widely used Javascript library with some helper functions. Many of them could be translated directly to rush.

[ ] chunk (for arrays and strings)
[x] compact (equivalent of filter(bool & (!)) if that was a valid syntax)
[ ] concat (accepting variable number of array arguments)
[ ] deburr (as Unicode NFD conversion)
[ ] flip
[ ] flatten (like concat but accepts array of arrays)
[ ] head (both arrays and strings)
[x] identity (as id)
[ ] initial (as init)
[x] invert (as an overload for rev for object arguments)
[x] keys (for objects, arrays, and strings (return array of indices for the latter two))
[ ] last (both arrays and strings)
[ ] now (possibly as time; may make sense to create a datetime/instant type)
[x] omit (for objects, arrays, and strings; keys as array)
[ ] pad (for both strings and arrays)
[ ] padEnd (as padright, for both strings and arrays)
[ ] padStart (as padleft, for both strings and arrays)
[x] pick (for objects, arrays, and strings; keys as array)
[x] reject (opposite of filter)
[x] sample(Size) (as sample, for arrays, strings, and objects (return random value for objects); sample size as first arg)
[x] shuffle (for arrays and strings)
[ ] tail (both arrays and strings)
[ ] uniq (both arrays and objects (objects uniq'd by values))
[ ] uniqBy (both arrays and objects (objects uniq'd by values))
[x] values
[x] words
[ ] zipObject (as object; it should accept either two same-sized arrays (keys and values), or a single array (alternating keys and values))
