A Collection library for when arrays are not enough

Installation

Usage

Include it in your script :

const Collection = require ('spark-collection')

It accepts an array as a argument :

const items = new Collection([1,2])
console.log(..items) // 1 2

Has function to add and remove unique items :

const items = new Collection([1,2,3])
items.remove(2)
console.log(..items) // 1 3
items.add(4)
console.log(..items) // 1 3 4
items.add(4) // do nothing since it exists
console.log(..items) // 1 3 4

You can use any function from arrays and it will return a new Collection if needed :

const items = new Collection([1,2,3,4])
const pair = items.filter( (item)=> item % 2 == 0 )
console.log(..pair) // 2 4
pair.add(6)
console.log(..pair) // 2 4 6
pair.pop()
console.log(..pair) // 2 4
