Traversing through a dictionary based on the sequence of element insertion

Within my programming project, there exists a dictionary that pairs unique question-ids with their corresponding questions. The issue at hand involves ensuring the order of elements when printing the contents of this dictionary. Each question-id consists of a random 10-digit string and this arrangement must be maintained throughout multiple printings. Should an element be deleted from the dictionary, it is to vanish while preserving the sequential order of remaining elements.

This task seems to necessitate the creation of a custom dictionary class; however, I wonder if there's another way?

var question_dic = {};
question_dic["2186242050"] = "Answer to life, universe and everything?";   //adding a key-value pair
delete question_dic[delete_key];   //remove delete_key key

Answer №1

In order to achieve this, it seems necessary to develop a custom dictionary class.

Indeed, that statement holds true. It is not recommended to utilize objects in that manner.

Nevertheless, the introduction of Maps in ES6 specifically addresses scenarios like this. Even if your scripts are not operating within an ES6 environment, you do not have to create your own dictionary class, as there are various polyfills available.
