Are circular references bad Javascript?
However, from a pure design point of view, circular referencing is still a bad thing and a code smell.

Is circular reference good or bad?
Circular references aren’t a bad thing in itself: you can use them to achieve complex calculations that are otherwise impossible to do, but first you must set them up properly. If you want to perform a calculation for which you need the last result to be a new input value for the calculation.
How to create a circularly referenced type in typescript?

The following excerpt explains why your attempt does not compile: Classes and interfaces can reference themselves in their internal structure… Your original example uses neither a class nor an interface; it uses a type alias.
Which is an example of a circular type reference?
The reference need not be a full code reference, simply the interfaces, but with interfaces defined in separate files. For example, let’s say I have two interfaces: Parent and Child. They are doubly-linked such that the parent has a collection of children and each child has a reference to the parent (as seen below).
How to solve circular dependency hell in typescript?

Using following 2 methods : This repo will helps me to find the place where circular occurs. This amazing article tells me to create internal.ts .
How are circular dependencies created in a compiler?
Circular dependencies are not created by importing libraries in a circle. They’re created by misusing the imported libraries. Having a boat.ts import Ocean and ocean.ts import Boat in the way I’ve described is perfectly fine and shouldn’t be any problem for any modern compiler.
