Description

Code Smells Made-Easy: Write Cleaner, Maintainable CodeBad code can slow down development, introduce bugs, and make maintenance a nightmare. But how do you identify these problems before they spiral out of control? Welcome to Code Smells Made-Easy, where you’ll learn to detect and eliminate bad coding practices, ensuring your software remains scalable, efficient, and maintainable.In this course, you'll dive deep into common code smells—subtle but harmful patterns that indicate deeper design issues. You’ll explore how to spot, analyze, and refactor smelly code using real-world examples and hands-on exercises.What You’ll LearnUnderstand what code smells are and why they matterIdentify common code smells like Long Methods, Large Classes, and Duplicated CodeLearn practical refactoring techniques to improve code qualityRecognize the impact of bad code on maintainability and performanceDevelop better coding habits to prevent code smells in the first placeWho Is This Course For?Developers (Beginner to Intermediate) who want to write cleaner codeSoftware Engineers who maintain legacy codebasesCode Reviewers & Team Leads who ensure best practicesAnyone interested in refactoring and improving software designWhy Take This Course?Hands-on Examples – See real-world code smells and how to fix themStep-by-Step Refactoring – Learn best practices for improving bad codeSave Time & Effort – Write code that is easier to read, debug, and maintainBoost Your Software Engineering Skills – Improve your design thinking and coding standardsBy the end of this course, you’ll be able to write cleaner, more maintainable code that reduces technical debt and improves software quality.
