what is const in js
In JavaScript, const is a keyword used to declare a variable that cannot be reassigned once it has been assigned a value. It is used to define constants, which are values that do not change throughout the program. Here's an example:
javascript Copy code
const PI = 3.14159;
console.log(PI); // Output: 3.14159
PI = 3.14; // Error: Assignment to constant variable
In the example above, PI is declared as a constant with the value of 3.14159. Any attempt to reassign a new value to PI will result in an error, as shown in the second line.
what does const in javascript mean?
In JavaScript, const is a keyword used to declare a variable that cannot be reassigned once it is assigned a value. It is used to define constants or values that should remain unchanged throughout the program.
Here is an example of how const is used in JavaScript:
javascript Copy code
const PI = 3.14159;
PI = 3.14; // This will result in an error, as you cannot reassign a constant variable.
The const keyword is useful when you want to ensure that a variable's value remains constant and should not be modified.
how to use math formulas in java script
In order to use math formulas in JavaScript, you will need to use the built-in Math object. The Math object provides several mathematical functions and constants. For example,
javascript Copy code
var x = Math.random();
var y = Math.PI;
This code will set x to a random decimal number between 0 and 1, and will set y to the constant PI.
You can use the Math object for more complex operations, such as square root and logarithm, as shown in this example:
javascript Copy code
var x = Math.sqrt(16);
var y = Math.log10(1000);
In this code, x will be given the value of the square root of 16, and y will be given the value of the logarithm of 1000.
For more information about mathematical functions and constants in JavaScript, you can review the MDN documentation on the Math object.

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. 👩💻🤝💻
