How To Compare Two Json Have The Same Properties Without Order

JSON (JavaScript Object Notation) is a popular data format used for exchanging information between servers and web applications. When dealing with JSON data, you might sometimes need to compare two JSON objects that have the same properties but are not necessarily in the same order.

Here's a simple method to compare two JSON objects in JavaScript without worrying about the order of properties.

First, you need to parse the JSON objects into JavaScript objects using the `JSON.parse()` method. This will allow you to work with the data in a more structured way.

const json1 = '{"name": "Alice", "age": 30}';
const json2 = '{"age": 30, "name": "Alice"}';

const obj1 = JSON.parse(json1);
const obj2 = JSON.parse(json2);

Now that you have the parsed objects, you can compare them by first checking if they have the same set of keys (properties). One way to achieve this is by converting the keys of both objects into arrays and then checking if the arrays are equal in length.

const keys1 = Object.keys(obj1).sort();
const keys2 = Object.keys(obj2).sort();

if (keys1.length !== keys2.length || keys1.join() !== keys2.join()) {
    console.log("JSON objects do not have the same properties.");
    return;
}

Next, you can iterate over the keys of one object and compare the values with the corresponding keys in the other object.

for (let key of keys1) {
    if (obj1[key] !== obj2[key]) {
        console.log("Values for property '" + key + "' are different.");
        return;
    }
}

console.log("JSON objects have the same properties with matching values.");

In this code snippet, we first ensure that both JSON objects have the same properties by comparing the sorted array of keys. Then, we iterate over the keys and check if the values are equal for each property.

Remember that this method only compares the top-level properties of the JSON objects. If your JSON objects contain nested objects or arrays, you might need to implement a recursive comparison function to handle those cases.

By following these steps, you can compare two JSON objects in JavaScript without being concerned about the order of properties. This approach can be useful when working with JSON data that might have properties arranged differently but contain the same information.
