Ways to implement Object.values() in JavaScript

Last Updated : 27 Dec, 2022

There is a method Object.values() which returns the values of JavaScript Object. Here we are going to see all other alternatives to this method with the help of JavaScript. Here a few approaches are discussed.

Using Object.keys() method and map() method
Using obj.hasOwnProperty() and push() method
Using Object.keys() method and map() method

Approach 1: Use the Object.keys() method to get the keys and then use the map() method to map the keys to the values and store the values in an array.

Example: This example implements the above approach.

html

<body style="text-align:center;">
    <h1 style="color: green">
        GeeksForGeeks
    </h1>
    <h3>
        Alternative version for Object.values() in JavaScript.
    </h3>
    <p id="GFG_UP">
    </p>
    <button onclick="gfg_Run()">
        Click Here
    </button>
    <p id="GFG_DOWN">
    </p>
    <script>
        var el_up = document.getElementById("GFG_UP");
        var el_down = document.getElementById("GFG_DOWN");
        var arr = [];
        var obj = {
            a: 'val_1',
            b: 'val_2'
        };
        el_up.innerHTML =
        "Click on the button to get the values.<br>Object = "
        + JSON.stringify(obj);
        
        function gfg_Run() {
            var val = Object.keys(obj).map(function(e) {
                return obj[e];
            });
            el_down.innerHTML = JSON.stringify(val);
        }
    </script>
</body>

Output:

Approach 2: Visit every property of the object by running a loop and push the value in an array each time. obj.hasOwnProperty() and push() method are used.

Example: This example implements the above approach.

html

<body style="text-align:center;">
    <h1 style="color: green">
        GeeksForGeeks
    </h1>
    <h3>
        Alternative version for Object.values() in JavaScript.
    </h3>
    <p id="GFG_UP">
    </p>
    <button onclick="gfg_Run()">
        Click Here
    </button>
    <p id="GFG_DOWN">
    </p>
    <script>
        var el_up = document.getElementById("GFG_UP");
        var el_down = document.getElementById("GFG_DOWN");
        var arr = [];
        var obj = {
            a: 'val_1',
            b: 'val_2'
        };
        el_up.innerHTML =
        "Click on the button to get the values.<br>Object = "
        + JSON.stringify(obj);
        
        function getValues(obj) {
            var ret = [];
            for (var i in obj) {
                if (obj.hasOwnProperty(i)) {
                    ret.push(obj[i]);
                }
            }
            return ret;
        }
        
        function gfg_Run() {
            el_down.innerHTML = JSON.stringify(getValues(obj));
        }
    </script>
</body>

Output:

Approach 3:(In ES6 format) Use the Object.keys() method to get the keys and then use the map() method to map the keys to the values and store the values in an array.

Example: This example implements the above approach.

html

<body style="text-align:center;">
    <h1 style="color: green">
        GeeksForGeeks
    </h1>
    <h3>
        Alternative version for Object.values() in JavaScript.
    </h3>
    <p id="GFG_UP">
    </p>
    <button onclick="gfg_Run()">
        Click Here
    </button>
    <p id="GFG_DOWN">
    </p>
    <script>
        var el_up = document.getElementById("GFG_UP");
        var el_down = document.getElementById("GFG_DOWN");
        var arr = [];
        var obj = {
            a: 'val_1',
            b: 'val_2'
        };
        el_up.innerHTML =
        "Click on the button to get the values.<br>Object = "
        + JSON.stringify(obj);
        
        function gfg_Run() {
            el_down.innerHTML = Object.keys(obj).map(e => obj[e]);
        }
    </script>
</body>
