uniqq

Removes all duplicates from multiple nested array recursively.

Usage

First install using npm:

npm install uniqq

Array Object

input parameters:
Then use it as follows:

• array is the array to remove items from
• key is the key of object with duplicate value

const removeDuplicates = require('uniqq');
const arrObj = [
  { name: 'Leonor' },
  { name: 'Esperanza' },
  { name: 'Leonor' },
  { name: 'Horacio' },
  { name: 'Leonor' },
  { name: 'Nicholas' },
  { name: 'Leonor' }
];

console.log(removeDuplicates(arrObj, key = 'name'));

//Prints:
//
//  [
//   { name: 'Leonor' },
//   { name: 'Esperanza' },
//   { name: 'Horacio' },
//   { name: 'Nicholas' }
// ]
//

Nested Array Object

This method remove all duplicate objects recursively base on object key
Then use it as follows:

const removeDuplicates = require('uniqq');
const arr = [{ id: 1, title: 'technology lovers' }, { id: 2, title: 'geeks' }, { id: 2, title: 'geeks' }, { id: 1, title: 'musics' }, {
    id: 4, jobs: [
        { id: 1, title: 'chef' },
        { id: 2, title: 'accountant' },
        { id: 2, title: 'teacher' },
        { id: 2, title: 'teacher' },
        { id: 2, title: 'teacher' },
    ], educations: [
        { id: 1, title: 'software engineer' },
        { id: 1, title: 'software engineer' },
        { id: 2, title: 'data science' },
        { id: 2, title: 'data science' },
        { id: 2, title: 'data science' },
        { id: 2, title: 'data science' },
        { id: 54, title: 'data science' },
        { id: 2, title: 'data science' },
        {
            fields: [
                {
                    main: [
                        { id: 1, title: 'software engineer' },
                        { id: 2, title: 'data science' },
                        { id: 2, title: 'data science' },
                        { id: 2, title: 'data science' },
                        { id: 2, title: 'data science' }
                    ]
                }
            ]
        }
    ]
}];

console.log(removeDuplicates(arr, 'title', true));

//Prints:
//
//  [
//     { id: 1, title: 'technology lovers' },
//     { id: 2, title: 'geeks' },
//     { id: 1, title: 'musics' },
//     {
//         id: 4,
//         jobs: [
//             { id: 1, title: 'chef' },
//             { id: 2, title: 'accountant' },
//             { id: 2, title: 'teacher' }
//         ],
//         educations: [
//             { id: 1, title: 'software engineer' },
//             { id: 2, title: 'data science' },
//             {
//                 fields: [
//                     {
//                         main: [
//                             { id: 1, title: 'software engineer' },
//                             { id: 2, title: 'data science' }
//                         ]
//                     }
//                 ]
//             }
//         ]
//     }
// ]
//

Note: if you don't want to remove duplicate objects recursively you can set nestedRemover parameter false as follow:

removeDuplicates(arr, 'title', false);

Array String

Then use it as follows:

const removeDuplicates = require('uniqq');
const strArr = ['alex', 'william', 'martin', 'sara', 'sara', 'max'];

console.log(removeDuplicates(strArr));

//Prints:
//
//  'alex', 'william', 'martin', 'sara', 'max'
//

Array Numbers

Then use it as follows:

const removeDuplicates = require('uniqq');
const numberArr = [111, 22, 33, 44, 55, 66, 77, 88, 88, 99, 10, 10, 10, 10];

console.log(removeDuplicates(numberArr));

//Prints:
//
//  111, 22, 33, 44, 55, 66, 77, 88, 99, 10
//
