Are you trying to mean "convertedName" in the variable name? I am not sure.

Hi, you can also do console.log(message. trim()).

const nameLength = name.length;
const message = "My name is " + convertetName + " and the length of my name " + nameLength;

Is there any special meaning to capitalize this variable particularly?
If no, I would suggest follow the camelcase guideline in naming.


function calculateSalesTax(price) {
let tax = price * TAX_RATE;

HI, for the variable TAX_RATE we can use camelcase like - taxRate. or you can avoid declaring the variable as well for that the code should be - function calculateSalesTax(price) {
let salestax = (price * 0.2)
return price + salestax;
}

well done. Keep it up

return price + tax;
}
