Dependency injection is crucial for decoupling code in software development. Coupled code leads to maintenance challenges, where changes in one module inadvertently affect others. To assess coupling levels, one must evaluate the interdependencies between modules, categorizing them from lightly to heavily coupled. Lightly coupled modules facilitate ease of maintenance and updates, while heavily coupled modules create complex interdependencies that complicate development. Avoiding coupled code is essential to reduce unintended consequences and ensure stability when modifying code.
Coupled code refers to a situation where changes in one module directly affect another, causing unexpected consequences or bugs, making maintenance difficult.
To determine coupling levels, one should analyze the dependencies between modules, considering how modifications to one module could impact others.
Lightly coupled code allows for easier changes and updates since modules operate independently, while heavily coupled code creates a web of interdependencies that complicate maintenance.
Maintaining decoupled code is crucial to ensure that changes in a particular module do not inadvertently disrupt the functionality of other modules.
