“Spaghetti code” is a term used to describe poorly organized, tangled, or intricately nested code that is notoriously difficult to comprehend, update, extend, and maintain. It usually refers to code that lacks proper organization, has complex or convoluted control flow, and violates the principles of good software design.
If you’re not careful, spaghetti code will creep into your application’s source code, no matter how simple or sophisticated your code might be. Eventually your code will become unreadable and challenging to work with, making it difficult to add new features, fix bugs, and maintain the code base over time.
