@monymike Just don’t capitalize the C in console. It has to be lowercase. :slight_smile:

Hey @Maverick23, hope you’re well.

Now the assignment is to read the chapter one of the eloquent JavaScript book, which is in this lesson: https://academy.ivanontech.com/products/javascript-programming-for-blockchain-developers/categories/1708561/posts/5735037

Hey guys! I hope this helps someone… for “Practice exercise - Loops, If-else & Boolean’s” lesson 23/38, exercise 28. It seems that the exercise is broken into 3 different parts. I tried to follow the instructions. When I looked at the answer it seems as if there is a part b). I was confused by this. It took me a minute going through the solution line by line but I figured out that it makes more sense for the problem being presented to be broken into part a) part b) and then 3. would be included in part b).

Hopefully that makes better sense! It helped me to see it this way in the end. :slight_smile:

Hey guys I’m having an issue with the “$” symbol in Atom not registering the the console; it is “not defined.” Does anyone else have this problem? I’m currently on Lesson 8 of the Javascript Next Level category. Thanks!

Hi @kyliezz, hope you are well.

Now I think you have to include jquery in your code to be able to use the $ sign which is used for jquery syntax.

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>

You only have to include that line into your head tag.

If you have any more questions, please let us know so we can help you! :slight_smile:

Thanks Carlos!

I promise I’m not crazy… I put the link in before and followed Ivan’s instructions for where to find it. But for some reason it took your link to make it work :upside_down_face:…

The Quiz ’ What is the result of this (10+22) % 3 Answer is 2

I understand the paragraph from the book but still don’t know how 2 is the correct answer ??

“There is one more arithmetic operator, which you might not immediately recognize. The % symbol is used to represent the remainder operation. X % Y is the remainder of dividing X by Y. For example, 314 % 100 produces 14, and 144 % 12 gives 0. The remainder operator’s precedence is the same as that of multiplication and division. You’ll also often see this operator referred to as modulo.”

in javascript, Practice exercise - Boolean’s & If,Else statements

  1. Tax in Ruritania

In the fictional country of Ruritania, the tax rules are such that:

  • if a person has an income <1000, then you pay 10% tax on the entire income,
  • and if the income >= 1000, then you pay a 10% tax on the first 1000 Euros and 30% tax on the rest of the income.
  1. Create a script that calculates and prints how many euros to pay in taxes. The script should read the income (which is assumed to be a decimal number) from user input.

var salary = prompt(“What is your income this month?”);

if(salary<1000){let tax = salary*0.1}

else {let tax = ((salary-1000)0.3)+(10000.1)}

console.log("your tax is " tax)

I am sure there is a different approach to take to this question, but I am curious to know why my code isn’t working
