What is the infinity global property in Javascript and when is it used?
In JavaScript, the Infinity global property represents a mathematical concept of infinity. It is a special value that represents a number that is greater than any other number.
The Infinity property is typically used in computations involving large numbers or mathematical operations that result in a value that is too large to be represented by a standard number data type. It can also be used to check if a number is infinite using the isFinite() function.
For example:
javascript Copy code
console.log(1 / 0); // Output: Infinity
console.log(Infinity + 1); // Output: Infinity
console.log(Infinity * 10); // Output: Infinity
console.log(Infinity === Infinity); // Output: true
console.log(isFinite(Infinity)); // Output: false
It's important to note that dividing a non-zero number by Infinity or performing operations involving Infinity may result in unexpected and non-numeric values.
what is Math in js
In JavaScript, "Math" is an object that provides mathematical functions and constants. It allows you to perform various mathematical operations like calculations, rounding numbers, generating random numbers, etc.
Here is an example of using the Math object to calculate the square root of a number:
javascript Copy code
let number = 16;
let squareRoot = Math.sqrt(number);
console.log(squareRoot); // output: 4
You can learn more about the Math object in JavaScript here: Math - JavaScript | MDN
Creating decimal numbers with JavaScript
Sure! In JavaScript, you can create decimal numbers using the decimal point. Here's an example:
javascript Copy code
let num = 3.14;
In this example, num is a variable that stores the decimal number 3.14.
You can perform mathematical operations with decimal numbers just like with whole numbers. For example:
javascript Copy code
let x = 2.5;
let y = 1.3;
let sum = x + y;
In this example, the variables x and y store decimal numbers, and the sum variable stores the result of adding them together.
I hope this helps! Let me know if you have any more questions.
Your task is to create a function that does four basic mathematical operations. The function should take three arguments - operation(string/char), value1(number), value2(number). The function should return result of numbers after applying the chosen operation.
In JavaScript:
javascript Copy code
const calculate = (operation, value1, value2) => {
switch (operation){
case "+":
return value1 + value2;
case "-":
return value1 - value2;
case "*":
return value1 * value2;
case "/":
return value1 / value2;
default:
return "Operation not recognized"
}
}
calculate("+", 10, 5); // returns 15
calculate("-", 10, 5); // returns 5
calculate("*", 10, 5); // returns 50
calculate("/", 10, 5); // returns 2
calculate("^", 10, 5); // returns "Operation not recognized"

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. 👩💻🤝💻
