Circular Dependencies
Circular dependencies occur when two or more modules, classes, or components depend on each other directly or indirectly, creating a cycle in the dependency graph. This is a common software design issue that can lead to problems like infinite loops, initialization errors, and increased coupling, making code harder to maintain and test. It is often encountered in object-oriented programming, module systems, and build processes.
Developers should learn about circular dependencies to avoid them in their codebases, as they can cause runtime errors, complicate debugging, and hinder modularity. Understanding this concept is crucial when designing systems with multiple interdependent components, such as in large-scale applications using frameworks like Angular or Node.js, to ensure clean architecture and prevent build failures. It is also important for optimizing dependency injection and module loading in languages like Java or Python.
