Create an array of items and then pass it to Set.
var Set = require('./set')
var set = new Set([0,1,1])
// And then when we get it
set.get() // [0,1]This module casts inputs into strings. Objects and Arrays are turned into JSON with JSON.stringify.
This makes this module fairly simple as it doesn't allow complex objects to be stored. However, given that Objects and Arrays are now JSONified, these objects can now be compared according to their JSON output. To make two objects unique, give them a different output for their toJSON method.
In a future version, this module would use a javascript Set as the datastructure and therefore won't have this limitation, but Sets are quite ready yet.
There are various Set functions available
Set#uniquegiven an array, return an array with all duplicates removed.
-
Set#containsreturn whether a given property is available. -
Set#emptyreturn whether the set in empty. -
Set#sizereturn the size of the Set. -
Set#getreturn the set as an Array. -
Set#addadd an item to the Set. -
Set#removeremove an item from the set. -
Set#clearremove all items from the set. -
Set#unionreturn a new set that is the union of the set with another one. -
Set#intersectreturn a new set that is the intersection of the set with another one. -
Set#differencereturn a new set that is the difference of the set with another one. -
Set#findreturn an array with all items that match the predicate.
