what is the difference between null and undefined
In most programming languages, both null
and undefined
mean basically the same thing - lack of a meaningful value. However, there are some subtle differences. In JavaScript, null
is an explicitly assigned value that means "no value", whereas undefined
is a variable that has not been assigned a value. Knowing the difference between null
and undefined
values can be important when deciding how to handle them, as certain functions and operators might behave differently for each. For more information, see this article.
javascript else function
The else
keyword in Javascript is used to execute a statement when the condition of an if
statement is false
. For example, you can set the condition of an if
statement with a comparison operator and then use an else
statement to respond when the condition is false:
javascript Copy code
if (x > y) {
// run if condition is met
} else {
// run if condition is not met
}
can you please explain jss functions to me? specifically the formatting for making buttons work?
JSS (JavaScript Syntax Style) is a framework that allows developers to create their own styling format in JavaScript. This can be used to create custom components like buttons. You will need to use functions to properly format your button components using JSS. You can read more about JSS and how to use it for styling buttons here.

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. 👩💻🤝💻
