Tell us what’s happening:

I’ve gone through 6 forums now and found similar problems. I’ve change my arguments and made sure the return is a mathematical return. My const is the only thing I question but the error is that I need to use addTwoNumbers as my function, which I have. I’ve reset the lesson 3 times and input the same thing but continue to get the same error.

Your code so far

const character = "#";
const count = 8;
const rows = [];

function padRow(name) {
  return name;
}

// User Editable Region

function addTwoNumbers(num1,num2) {
  num1 = 5;
  num2 = 10;
  return num1 + num2;
};
const sum = addTwoNumbers(num1,num2);
console.log(sum);

// User Editable Region


const call = padRow("CamperChan");
console.log(call);


for (let i = 0; i < count; i = i + 1) {
  rows.push(character.repeat(i + 1))
}

let result = ""

for (const row of rows) {
  result = result + "\n" + row;
}

console.log(result);

You aren’t passing arguments to the function correctly.

You can’t pass num1 and num2 as arguments to the function, since those variables don’t exist outside the function.

3

How would I get them to exist outside the function? Creating a ‘const’ or ‘let’ for them?

4

like this?
var num1 = 5;

var num2 = 10;

function addTwoNumbers(num1,num2) {

num1 = 5;

num2 = 10;

return num1 + num2;

};

const sum = addTwoNumbers(num1,num2);

console.log(sum);

5

They don’t need to exist outside the function at all. They take the values that you pass to the function as arguments.

6

I get the error of return should be the sum of 2 numbers with this opotion:

function addTwoNumbers() {

return 5 + 10;

}

const sum = addTwoNumbers();

console.log(sum);

7

Your function should have 2 parameters.

This function should take two arguments

The function needs to add any two numbers. Your function only adds 5 and 10.

Call the function with 2 numbers.

calling your addTwoNumbers function with 5 and 10 as the arguments

You should call your function with the arguments 5 and 10, but it should also work with 1 and 2 or 30 and 40.

const sum = addTwoNumbers();

You are calling your function with zero arguments.

Thank you so much. I was overthinking it for some reason and was thinking I needed a const over a var.

Overthinking it is so often the case!

Only advice I can give is to read each line of the instructions carefully and make sure you’ve implemented each one. Really take it step by step. You could even re-write the instructions as bullet points if it helps.

  • Declare a function named addTwoNumbers.

  • This function should take two arguments and

  • return the sum of those two arguments.

  • Then declare a sum variable and

  • assign it the value of calling your addTwoNumbers function

  • with 5 and 10 as the arguments.

  • Log the sum variable to the console.
