How to Write Effective Comments in JavaScript Code

JavaScript comments are explanatory notes within code, ignored by browsers but crucial for developers. They improve code readability and maintainability, especially in larger projects. There are two types: single-line comments, using //, and multi-line comments, using /* and */. Single-line comments are ideal for brief explanations on individual lines. Multi-line comments are suited for more detailed explanations spanning multiple lines. Comments can also temporarily disable code sections during testing, a process called "commenting out." Effective comments are concise, explain the purpose of code, avoid redundancy, and are kept up-to-date. Following these best practices enhances code clarity and collaboration. Using comments consistently is a valuable habit for beginner and experienced JavaScript developers alike. Well-commented code promotes better understanding and easier maintenance.
