collection-iterator v1.2.1

Collection-Iterator

Description

When using a collection like list or set, we need to access each element using a loop and access and then apply certain functionality on each element \ Collection-Iterator saves you from implementing the code to access each element in the collection\ The best thing about Collection-Iterator is, you dont have to access all the elements at once and store it in a variable, instead you can access one element and then access another later in the code. It is not only restricted to accessing the next elements, but the user can also access the previous element in sequential order\ For example

const newCollection = new Stream([4,5,6])
console.log("First element in the collection", newCollection.iterator()) //logs 4
//Other functionalities
console.log(newCollection.iterator()) //logs 5
console.log(newCollection.previous()) //logs 4

Installation and Usage

Run npm install collection-iterator to install the package \ In your project run the following command to use the iterator

const { Stream } = require('collection-iterator')

This above command imports an function(Object) called Stream which has the required properties to run the iterator

Using Stream and new keyword

In order to use the iterator, we need to create an object with a property names collections which will store our array/list or set

const myCollection = new Stream([4,5,6])

Now we can run the iterator function which gives out each element as the output\

We can also pass a set as input

const mySetCollection = new Stream({1,2,{a:10,b:20}});
