How to make a unique array of arrays in Javascript without any repeated elements

Hello fellow programmers! I'm diving into Javascript and facing a little challenge that I need help with.

Let me share some data that I'm dealing with:

<pre>
[
  [
    {
      "id": 2759178563,
      "title": "Ergonomic Paper Computer",
      "handle": "ergonomic-paper-computer",
      "body_html": "Enable turn-key infrastructures",
       ...
     ]
   ],
  ...
]
</pre>

Now, let's take a look at the code snippet I have so far:

import { Injectable } from '@angular/core';
...

@Injectable()
export class ShopifyService {

    constructor (
        private http: Http
    ) {}

    // Methods to fetch, extract, handle data

    public findProducts(archetypes) {
        return this.fetchProducts().then(
                products => {
                    var result = [],
                        fetchedResponse = [];

                    for (var i = 0; i < archetypes.length; i++) {
                        ...
                    }
                    return result;
                },
                error => this.errorMessage = <any>error
            )
    }

    ...

    public findSingleProductVariant() {
        var result = [];
        ...

        return result;
    }
}

I've managed to organize my data into arrays of two-dimensional arrays, categorizing them by type. Each category contains multiple variants. Now, I need to enhance my findSingleProductVariant method to filter out unique pairs of computer and keyboard variants, calculate their prices, and ensure they are not repeated. The condition is that the total price should be less than 1000 before moving on to new pairs. How can I achieve this logic efficiently?

Answer â„–1

One important concept to keep in mind is the inability to directly compare objects and obtain meaningful results, for example:

{'Apple', 'Banana'} === {'Apple', 'Banana'}

This comparison will result in false, (similarly, using Array.indexOf() will not yield expected outcomes due to its strict comparison nature).

Therefore, when dealing with an array of arrays, it becomes necessary to implement two nested loops to accurately compare primitive values.
