How can I get an array of objects containing a certain property value that are nested in another object in JavaScript? [closed]

I have an object with a bunch of nested objects, some of which have their own nested objects. I need to write a function that accepts the outermost object and returns an array of all objects that are nested inside it that satisfy a given condition. I've been banging my head against the desk for an hour with only vague ideas but at this point I just don't know how to solve this.

It works perfectly fine dose anyone know the reason about it? cv = KFold(n_splits = 10) all_loss = [] for i in range(9): # 1st for loop over polynomial orders poly_order = i X_train = make_polynomial(x, poly_order) loss_at_order = [] # initiate a set to collect loss for CV for train_index, test_index in cv.split(X_train): print('TRAIN:', train_index, 'TEST:', test_index) X_train_cv, X_test_cv = X_train[train_index], X_test[test_index] t_train_cv, t_test_cv = t[train_index], t[test_index] reg.fit(X_train_cv, t_train_cv) loss_at_order.append(np.mean((t_test_cv - reg.predict(X_test_cv))**2)) # collect loss at fold all_loss.append(np.mean(loss_at_order)) # collect loss at order plt.plot(np.log(al...
