Given an array of objects and the task is to convert the object values to an array with the help of JavaScript. There are two approaches that are discussed below:

Approach 1:

We can use the map() method and return the values of each object which makes the array.

  • Example: html
    
    <html>
    <head>
        <title>
            Convert a JS object to an array using JQuery
        title>
        <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.0/jquery.min.js">
        script>
    head>
    <body style="text-align:center;">
        <h1 style="color:green;">
            GeeksForGeeks
        h1>
        <p id="GFG_UP">p>
        <button onclick="myGFG()">
            Click Here
        button>
        <p id="GFG_DOWN">p>
        <script>
            var up = document.getElementById("GFG_UP");
            var JS_Obj = {
                1: ['gfg', 'Gfg', 'gFG'],
                2: ['geek', 'Geek', 'gEEK']
            };
            up.innerHTML = "Object - [" 
                    + JSON.stringify(JS_Obj) + "]";
            
            var down = document.getElementById("GFG_DOWN");
            
            function myGFG() {
                var array = $.map(JS_Obj, function (val, ind) {
                    return [val];
                });
                down.innerHTML = array;
            }
        script>
    body>
    html>
    
  • Output:
UsingMapMethod
Utilizing the map() Method to Extract and Display Values from Each Object within an Array

Approach 2:

The Object.keys() method is used to get the keys of object and then those keys are used to get the values of the objects from the array.

  • Example: html
    
    <html>
    <head>
        <title>
            Convert a JS object to an array using JQuery
        title>
        <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.0/jquery.min.js">
        script>
    head>
    <body style="text-align:center;">
        <h1 style="color:green;">
            GeeksForGeeks
        h1>
      <p id="GFG_UP">p>
        <button onclick="myGFG()">
            Click Here
        button>
        <p id="GFG_DOWN">p>
        <script>
            var up = document.getElementById("GFG_UP");
            
            var JS_Obj = {
                1: ['gfg', 'Gfg', 'gFG'],
                2: ['geek', 'Geek', 'gEEK']
            };
            
            up.innerHTML = "Object - [" 
                + JSON.stringify(JS_Obj) + "]";
    
            var down = document.getElementById("GFG_DOWN");
            
            function myGFG() {
                var arr = Object.keys(JS_Obj)
                    .map(function (key) 
                    { return JS_Obj[key]; });
                    
                down.innerHTML = arr;
            }
        script>
    body>
    html>
    
  • Output:
    UsingObjectKey
    Using the Object.keys() Method to Extract and Display Object Keys and Values
