dedupe
removes duplicates from your array.
Installation
$ npm install dedupe
Usage
primitive types
var dedupe = require('dedupe')
var a = [1, 2, 2, 3]
var b = dedupe(a)
console.log(b)
//result: [1, 2, 3]
complex types
Here the string representation of the object is used for comparism. Internal JSON.stringify
is used for serialization.
That means that {}
is considered egal to {}
.
var dedupe = require('dedupe')
var aa = [{a: 2}, {a: 1}, {a: 1}, {a: 1}]
var bb = dedupe(aa)
console.log(bb)
//result: [{a: 2}, {a: 1}]
complex types types with custom hasher
You can use a custom hasher to overwrite the default behaviour.
var dedupe = require('dedupe')
var aaa = [{a: 2, b: 1}, {a: 1, b: 2}, {a: 1, b: 3}, {a: 1, b: 4}]
var bbb = dedupe(aaa, value => value.a)
console.log(bbb)
//result: [{a: 2, b: 1}, {a: 1,b: 2}]
