Enriching JSON Data with Additional Values

Enriching JSON Data with Additional Values

Imagine having a JSON data set structured like this:

{ "fruits": {
    "apple": {
        "color": red,
        "size": small
    }
    "orange": {
        "color": orange,
        "size": small
    }
}

Is there a way to dynamically add a name attribute to each fruit object in the dataset using JavaScript? I want them to look like this:

{ "fruits": {
    "apple": {
        "color": red,
        "size": small,
        "name": apple
    }
    "orange": {
        "color": orange,
        "size": small,
        "name": orange
    }
}

I understand that having both id and name values as the fruit name may seem redundant, but it's necessary for the functionality of the program I'm developing. Any advice on how to achieve this?

Answer №1

First and foremost, ensure that your properties are enclosed in quotations, unless they happen to be variables. Here's an example:

"banana": {
    "color": "yellow",
    "size": "medium"
}

Remember to include a comma between each fruit in your list.

To assign a new property with the name of each fruit, you can loop through them like this:

for (var prop in data.fruits) {
    if (data.fruits.hasOwnProperty(prop)) {
        data.fruits[prop].name = prop;
    }
}

The use of square bracket notation allows for accessing dynamic or variable property names, simplifying the task of setting the name property. Refer to this resource for guidance on iterating through object properties.

Below is a snippet that demonstrates how this code works:

var data = {
    "fruits": {
        "strawberry": {
            "color": "red",
            "size": "small"
        },
        "kiwi": {
            "color": "green",
            "size": "small"
        }
    }
}

for (var p in data.fruits) {
    if (data.fruits.hasOwnProperty(p)) {
        data.fruits[p].name = p;
    }
}

console.log(data);
