How to reorganize the json data and classify them according to the type of test questions?

the final rendering to the page is based on single selection, multi-selection, judgment, etc., to solve?

Json javascript

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?
