How can I flatten nested data structures in JavaScript?

How can I flatten nested data structures in JavaScript?

You can use the Array.prototype.flat() method to flatten arrays. For example, array.flat(depth) flattens the array up to the specified depth.

What if I have an object with nested arrays?

You can create a recursive function to handle objects and arrays. Would you like an example?

Yes, please provide an example of that.

Here's a simple example:

function flatten(obj) {
    let result = {};
    for (let key in obj) {
        if (Array.isArray(obj[key])) {
            result[key] = obj[key].flat();
        } else if (typeof obj[key] === 'object') {
            result[key] = flatten(obj[key]);
        } else {
            result[key] = obj[key];
        }
    }
    return result;
}

This function flattens nested objects and arrays.

That looks great! Can this function handle deeply nested structures?

Yes, it can handle deeply nested structures as long as you adjust the recursion accordingly. Would you like to see a more complex example?
