Combine two distinct associative arrays into a single associative array containing an array with two associative arrays using JavaScript

How can I combine two arrays into a single array that contains more complex data structures with matching values on both sides?

 var arr1 = [{
  "id": "4",
  "ip_address": "127.0.0.1",
  "username": "superuser",
  "password": "$2y$08$awherOdjNPRoDHAiNBGZNuA92UGfT7jsIpsMMcNnyyJMxBA8Ug9q6",
  "salt": null,
  "email": "<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="1764626772655776737a7e793974787a">[email protected]</a>",

  }],
  "$$hashKey": "object:11"
}];
var arr2 = [{

Answer №1

If you have two arrays named arr1 and arr2, you can combine them like this:

var $combinedArray = arr1.concat(arr2);

Now, if you want $combinedArray to be an array with two elements, each one being a separate array, you would use:

var $combinedArray = [arr1, arr2];

However, this approach may not align with your desired outcome and could result in confusion.

Answer №2

let firstArray = [10, 20];
let secondArray = [30, 40, 50];

Array.prototype.push.apply(firstArray,secondArray);
console.log(firstArray);

let firstArray = [{

let $users = firstArray.concat(secondArray);
console.log($users);

Combine the content of both arrays by utilizing the concat method

Answer №4

let numbersArr = [/\*numbers\*/];

const lettersArr = [/\*letters\*/];

// Representing values as mentioned:

const $data = numbersArr.concat(lettersArr); //[firstNumbers, firstLetters]

// Organizing values based on category:

const $data = [numbersArr, lettersArr]; //[[firstNumbers], [firstLetters]]
