What is a comment in JavaScript?
In JavaScript, a comment is a piece of text that is used to provide explanations or annotate code. Comments are not executed by the computer and are ignored by the JavaScript interpreter. They are used to improve code readability, make notes, or prevent certain code from running during testing or debugging.
There are two types of comments in JavaScript:
Single-line comments: They are denoted by "//" and are used to comment a single line of code. Example:
javascript Copy code
// This is a single-line comment
Multi-line comments: They are denoted by "/* */" and can span multiple lines. They are used to comment multiple lines of code. Example:
javascript Copy code
/*
This is a
multi-line comment
*/
Comments are helpful for developers to understand code and for other developers who may be working on the same codebase.
how to write comments in CSS
To write comments in CSS, you can use the /* comment / syntax. Anything enclosed between / and */ will be treated as a comment and will not affect your CSS code. Comments are useful for adding explanations, notes, or reminders in your code. Here's an example:
css Copy code
/* This is a CSS comment */
p {
color: red; /* This sets the color of paragraphs to red */
}
In the above example, the comment is indicated by /* and */. The CSS code inside the comment is not executed by the browser, so it does not affect the styling of the paragraph element. Comments are a great way to make your code more readable and maintainable.

AI stands for Artificial Intelligence. AI bots are able to learn from conversations with users and expand their knowledge this way.
SheCodes Athena will help you with technical questions about your code using artificial intelligence to find the answer. Imagine a super powerful human who has memorized everything on the internet and can access that knowledge in a matter of seconds. 🤯
SheCodes Athena can answer most coding-related questions, even complicated ones! It can even find bugs in your code and tell you how to fix them in just a few seconds. Impressive, right?
Just remember we're still in testing mode so the AI may return strange or incorrect replies. Feel free to message us if this happens!
SheCodes Athena can only reply to coding-related technical questions. The same type of questions you would ask in the channels on Slack.
For questions that are not coding-related, write us here 😃
You should treat Athena like a SheCodes team member, so always be polite! 😊 Ask your questions as detailed as possible, just like you would do on Slack.
Here are some examples:
- Prettier isn't working on my VS Code. How do I fix this?
- How do I make bullet points with different colors using the list element?
- My code in Codesandbox is having some issues. Can you please tell me what the issue is? [Include the link to your Codesandbox]
For now, SheCodes Athena is limited to 5 questions per day for each student.
In that case, you can either ask SheCodes Athena a follow-up question, or you can post on the designated weekly channel on Slack!
Our technical assistants are still available on Slack and are always happy to help! 😍💪
Remember, questions are limited to 1000 characters.
- If you're working with an HTML file: Post a snippet of your code related to the issue you're having (just copy the code and paste it into the question box).
- If you're working with Codesandbox: Good news, you can just post the link to your Codesandbox and the AI Assistant will be able to view your code.
- If you have a longer question that would require an entire HTML file or more than 1000 characters, post it in the designated weekly channels on Slack! 😃
Athena was the Greek goddess of wisdom, among other elements. She received her name from the city of Athens, which she is known for protecting.
Much like the goddess Athena, SheCodes Athena is also incredibly wise and can solve complicated coding puzzles in a matter of seconds! 😍
Not likely. AI can automate tasks and make developers' jobs more efficient but it can't fully replace the human ability to deal with complex software. And AI will still require human developers to supervise and improve it further.
So developers may see their tasks change but they won't be replaced by AI. 👩💻🤝💻
