How can I flatten a nested object in JavaScript?

You can use recursion or the reduce method to flatten a nested object. Would you like a code example?

Yes, please provide a code example.

Here's a simple example:

function flattenObject(obj) {
    const result = {};
    for (const key in obj) {
        if (typeof obj[key] === 'object' && obj[key] !== null) {
            const temp = flattenObject(obj[key]);
            for (const tempKey in temp) {
                result[`${key}.${tempKey}`] = temp[tempKey];
            }
        } else {
            result[key] = obj[key];
        }
    }
    return result;
}

This function will flatten the nested object into a single level.

What if the object has arrays in it?

You can modify the function to handle arrays by iterating through them and flattening their contents as well. Would you like to see that?
