The thing that annoys me, if this is a day 0 course.. how am I supposed to know about different methods?

console.log(firstInteger + +secondInteger) console.log(firstDecimal + +secondDecimal) console.log(firstString + secondString)

function performOperation(secondInteger, secondDecimal, secondString) { const firstInteger = 4; const firstDecimal = 4.0; const firstString = 'HackerRank ';

const sumIntegers = firstInteger + Number(secondInteger);
console.log(sumIntegers);

const sumDecimals = firstDecimal + Number(secondDecimal);
console.log(sumDecimals);

const concatenatedString = firstString + secondString;
console.log(concatenatedString);

}

console.log(parseInt(secondInteger) + firstInteger); console.log(parseFloat(secondDecimal) + firstDecimal) console.log(firstString + secondString);

`

I have to be missing something pretty obvious because it says I've passed test case 0 but I'm failed test case 1 and test case 2. However, I'm not even seeing a test case 1 or 2.

What am I missing?
