Comments – The Key to Engaging Your Audience and Boosting Your Website\’s Success

Comments in programming are lines of code that are not executed by the computer but are meant for human readers. They provide essential information about the code, helping developers understand the purpose, functionality, and logic behind the code. Comments can explain complex algorithms, document code changes, or provide clarity to future developers who may need to modify or maintain the code.

In HTML, comments are written inside <!– –> tags. They can be placed anywhere within the HTML code. They will not affect how the browser renders page pages. Comments are often used to add notes, reminders, or explanations to the code, making it easier for developers to navigate and understand the structure and purpose of the webpage.

Comments are crucial in development as they improve code readability and maintainability. They allow developers to annotate their code, making it self-explanatory and more accessible to comprehend, especially for larger projects or when collaborating with other developers. Furthermore, comments help with debugging, allowing developers to temporarily disable or isolate specific code sections for testing or troubleshooting purposes.

Understanding the Purpose of Comments


Comments are an essential programming tool that allows developers to add explanatory notes within their code. The computer does not interpret these notes but serves as a way for the programmer to provide context and clarification for human readers.

Comments are typically used to:

  • Explain the purpose of specific code sections or functions
  • Provide information on how the code works
  • Document potential issues or areas that need improvement
  • Collaborate and communicate with other developers

Developers can use comments effectively to make their code more readable and maintainable. They can also help future developers who may need to modify or debug the code, as comments provide valuable insights into the original author\’s intent.

Comments can also temporarily turn off some code during testing or debugging. This can be particularly useful when troubleshooting and trying to isolate the cause of a problem.

It is essential to follow best practices when using comments. Keep them concise and focused on providing relevant information. Avoid unnecessary or redundant comments that can clutter the code and make it harder to read. Additionally, constantly update or remove comments that are no longer accurate or relevant.

Overall, comments play a crucial role in the development process by improving code readability, facilitating collaboration, and aiding in troubleshooting. By using comments effectively, developers can enhance their code and make it more understandable for themselves and others.

What Are Comments in Programming?


In programming, comments are lines of text added to code to provide explanations, descriptions, or instructions. Comments are not executed by the computer and are ignored by the programming language\’s interpreter or compiler. They are solely for the benefit of the programmers and developers who read and maintain the code.

Why are comments used?

Comments are essential to programming as they help improve code quality, clarity, and maintainability. They serve various purposes, including:

  • Providing explanations of complex or hard-to-understand code sections.
  • Documenting code and giving information about its purpose, functionality, or expected input/output.
  • Helping other programmers understand and work with the code.
  • Making it more accessible to debug and troubleshoot code by providing notes and observations.

How are comments written in programming languages?

The syntax for writing comments varies between programming languages. However, most languages use similar conventions for single-line and multi-line comments.

Language Single-line comment syntax Multi-line comment syntax
JavaScript // Comment /* Multi-line comment */
Python # Comment “”” Multi-line comment “””
C++ // Comment /* Multi-line comment */
Java // Comment /* Multi-line comment */

It is important to note that comments should be used sparingly and only when necessary. Over-commenting can make code harder to read and maintain. Additionally, comments should be kept up-to-date to ensure they accurately reflect the code they are associated with.

Best Practices for Writing Comments

When it comes to writing comments in your code, following best practices can significantly improve the readability and maintainability of your codebase. Here are some guidelines to keep in mind:

  • Keep comments concise and clear: Comments should provide additional information or explanation about the code, but they should not be longer than necessary. Stick to the point and use plain language.
  • Use comments to explain why, not what: Comments are most valuable when they provide insights into the reasoning behind certain decisions or code implementations. Focus on the why rather than repeating what the code does.
  • Avoid obvious comments: It\’s unnecessary to comment on every line of code that is self-explanatory. Instead, focus on commenting sections of code that might be harder to understand or have complex logic.
  • Update comments when changing code: Review and update the associated comments whenever you modify or refactor your code. Outdated or misleading comments can confuse and make the code harder to maintain.
  • Use proper grammar and spelling: Take the time to write comments with correct grammar, spelling, and punctuation. This makes your code look more professional and enhances readability.
  • Consider future readers: Remember that other developers might read your code or even yourself. Write comments that are helpful and easy to understand for anyone who comes across the codebase.
  • Comment complex or non-intuitive code: If you have a piece of incredibly complex or non-intuitive code, use comments to explain its logic or reasoning. This can save time for anyone who needs to understand or modify the code later.
  • Avoid leaving commented-out code: Instead of leaving old or unused code commented out in your files, consider using version control systems like Git to track changes. Commented-out code can make the codebase cluttered and confusing.
  • Be consistent with comment style: Choose a consistent style for your comments and stick to it throughout the codebase. This includes things like indentation, capitalization, and punctuation.
  • Use comments sparingly: While comments are helpful, it\’s still important to write clean and self-explanatory code. Aim to make your code as readable and understandable as possible without the need for excessive comments.

By following these best practices for writing comments, you can improve your codebase’s overall quality and maintainability, making it easier for others (and yourself) to understand and work with the code in the long run.

Choosing Descriptive Comment Names

When writing comments in your code, it is essential to choose descriptive comment names that convey the purpose and functionality of the code they are referencing. Comment names should provide meaningful information and make it easier for other developers (including your future self) to understand the code.

Here are some guidelines to consider when choosing descriptive comment names:

1. Be Specific

Choose comment names that accurately describe the code they are associated with. Avoid generic or vague comment names that do not provide any meaningful insight. For example, instead of using a comment like “// Calculate result\,” consider using “// Calculate the sum of two numbers\.” This provides more information about what the code is doing and makes it easier to follow.

2. Keep it Concise

Avoid using excessively long comment names that become difficult to read and understand. Use clear and concise comment names that capture the essence of the code. If the comment becomes too long, it may be a sign that the code must be refactored or simplified.

3. Use Proper Capitalization

Follow standard naming conventions when choosing comment names. Use proper capitalization and formatting to make the comments more straightforward to read. For example, use title or sentence case for longer comment names and lowercase for shorter ones.


// This function calculates the total sum of an array

// This helper function checks if a number is prime

4. Consider the Audience

Think about who will be reading your comments. Will it be other developers working on the same project? Your future self? Make sure the comment names are straightforward and understandable to the intended audience. If the code is part of a more extensive system, consider including additional context or references to related code.

5. Update and Maintain

As the code evolves, update the comment names accordingly. If the functionality of the code changes, update the comment names to reflect the new purpose accurately. This will ensure that the comments remain helpful and relevant.

In conclusion, choosing descriptive comment names is essential for writing clean and maintainable code. Following these guidelines can make your code more readable and understandable for yourself and other developers.

Keeping Comments Concise and Relevant

A critical aspect of writing good comments for code is to keep them concise and relevant. Comments should provide helpful information and clarification without being overly verbose or distracting.

Conciseness is key

When writing comments, it\’s essential to be concise and avoid unnecessary jargon. A comment should get straight to the point and clearly explain the code it pertains to. Avoid using excessive words or elaborate descriptions that could make it harder to understand.

By keeping comments concise, you can make them easier to read and comprehend, especially when revisiting the code at a later time. This saves time for yourself and other developers who may need to work with your code.

Relevance ensures understanding

In addition to being concise, comments should be relevant to the code they refer to. It\’s essential to provide comments that explain the purpose, functionality, or implementation details of the code, as this can significantly enhance understanding.

Irrelevant comments can be confusing and may even lead to misunderstandings. Comments should always address the context in which the code is used and provide information that will help maintain the modification of the future.

One way to ensure relevance is to consider the target audience of the code. Are you writing comments for other developers or your future self? Understanding who will read the code can help you tailor the comments to their needs and level of expertise.

Tip: Regularly review your comments and remove any outdated or redundant information. Keeping comments up-to-date ensures that they remain concise and relevant throughout the lifecycle of the code.
