Full path of a json object

Question

I\'m trying to flatten an object where the keys will be the full path to the leaf node. I can recursively identify which are the leaf nodes but stuck trying to construct the

Using newest JS features like Object spread and Object.entries it should be pretty easy:

function flatObj(obj, path = []) {
    let output = {};

    Object.entries(obj).forEach(([ key, value ]) => {
        const nextPath = [ ...path, key ];

        if (typeof value !== 'object') {
            output[nextPath.join('.')] = value;

            return;
        }

        output = {
            ...output,

            ...flatObj(value, nextPath)
        };
    });
}

Please note that this code is probably not the most optimal one as it copies the object each time we want to merge it. Treat it more as a gist of what would it look like, rather than a complete and final solution.
