How do I write this recursive function to find the max depth of my object?

Question

I\'m trying to write a function that will loop through my object and return the level depth of the object.

For example, if I ran the function on this object:

I have changed your code a bit to work as you want it to:

function getDepth(node, depth = 0) {
    if (!!node.children && node.children.length > 0) {
        var childDepths = [];
        depth++;

        for (var i = 0; i < node.children.length; i++) {
            childDepths.push(getDepth(node.children[i]));
        }
        return depth + Math.max(...childDepths);
    }

    return depth;
}

var depth = getDepth(root);

console.log('currentMaxDepth', depth);
console.log('root', root);

The trick is to measure depths of siblings on the same level and than pick the deepest of them. Here's also a jsfiddle: https://jsfiddle.net/2xk7zn00/
