nub v1.0.0
nub
Return all the unique elements of an array. You can specify your own uniqueness
comparison function with nub.by
too.
These work like haskell's
nub
and
nubBy
functions in
Data.List.
example
$ node
> var nub = require('nub')
> nub([1,2,2,3,1,3])
[ 1, 2, 3 ]
> nub.by([ 2, 3, 5, 7, 8 ], function (x,y) { return x + y === 10 })
[ 2, 3, 5 ]
methods
var nub = require('nub')
nub(xs)
Return a new array with all the uniqe elements in xs
.
Uniqueness is calculated ===
style so the types matter.
nub.by(xs, cmp)
Use cmp(x,y)
function to compare elements instead of the default.
cmp
should return whether the two elements are equal as a boolean.
install
With npm do:
npm install nub
To use nub in the browser, use browserify or fetch a UMD build from browserify CDN.
