Hey, don't we need to add i < itemsCount condition in line 23? https://gist.github.com/AjithPanneerselvam/c40d2daf36862fc1faabd915d79722ee#file-questiongroup-js-L23

However, I think the end survey object will save us. Just want to confirm with you dude.

Yaa nanu End survey irukunu dha vitten but better to add in case of bad data la?

Dude, the code is clean. Just did few reordering of statements and some formatting.

Unga amma mela sathiyama? Line 33 andha decrement panradhu manasu uruthudhu, any other idea?

If you are badly worried about it, then see how this looks

while(questionFlow[i+1].type == itemTypeQuestion && questionFlow[i+1].depth == (branchDepth + 1)) {
                i += 1
                item = questionFlow[i];

                const questionGroupItem = {
                    order: itemOrder, 
                    id: item.id 
                };
                
                questionGroupItems.push(questionGroupItem);
                itemOrder += 1;
                item = questionFlow[i];
}
