Defining attributes on objects at runtime, outside of their established structure, has been discouraged. For instance, adding a property like `myObject.newProperty = “someValue”` to an object that doesn’t inherently possess `newProperty` is now considered problematic. This practice often leads to code that is harder to maintain, debug, and reason about.
Standardized object structures improve code predictability and maintainability. Explicitly defining properties promotes clearer code contracts and facilitates static analysis. Historically, dynamically adding properties was common, but modern programming practices emphasize stricter object models. This shift enhances code reliability and interoperability, particularly in larger projects and collaborative environments. It also allows for better optimization by compilers and interpreters.
