Combines a list of arrays, returning a single array with unique values, using strict equality for comparisons.
Install with npm:
$ npm i arr-union --save
This library is 10-20 times faster and more performant than array-union.
See the benchmarks.
#1: five-arrays array-union x 511,121 ops/sec ±0.80% (96 runs sampled) arr-union x 5,716,039 ops/sec ±0.86% (93 runs sampled) #2: ten-arrays array-union x 245,196 ops/sec ±0.69% (94 runs sampled) arr-union x 1,850,786 ops/sec ±0.84% (97 runs sampled) #3: two-arrays array-union x 563,869 ops/sec ±0.97% (94 runs sampled) arr-union x 9,602,852 ops/sec ±0.87% (92 runs sampled)
var union = require('arr-union'); union(['a'], ['b', 'c'], ['d', 'e', 'f']); //=> ['a', 'b', 'c', 'd', 'e', 'f']
Returns only unique elements:
union(['a', 'a'], ['b', 'c']); //=> ['a', 'b', 'c']
