Circular dependency can create many redundant effects in software programs. The very first among them in terms of design is the tight coupling between mutually dependent modules, which results in reusing an individual module becoming more difficult or impossible. In general, there are several reasons why you should avoid circular references between objects. It creates the following problems:
- No dependency hierarchy and no reusability: Generally, we quantify the code with the layer it is at; for example, high level, low level, and so on. Every layer should only set a dependency (if any) on the layers below it. Normally, when you define dependency between modules, a dependency graph or hierarchy will be created, ...
