do you mean to sort by .room.sorting Type ?

suppose there is a variable questions in the array you give, and collection

is sorted.
var collection = {};

questions.forEach(ques => (collection[ques.question.questionType] = collection[ques.question.questionType] || []).push(ques));

write separately and read more clearly

var collection = {};

questions.forEach(ques => {
  collection[ques.question.questionType] = collection[ques.question.questionType] || [];
  collection[ques.question.questionType].push(ques);
});

I think you want to traverse it for different questionType processing?
