Tell us what’s happening:

I don’t know why code isn’t working. Says function and sum variable is not defined even tho they are.

Your code so far

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

function padRow(name) {
  return name;
}

// User Editable Region

function addTwoNumbers(a + b){
  const sum = addTwoNumbers(5 + 10);
}
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);

hi there!
a plus b as an argument, throwing error. that means you sum that two parameters as argument.

3

This function should take two arguments and return the sum of those two arguments.

4

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.

5

should it be like this then? It’s not really clearly written how to do this step

addTwoNumbers(a, b)
6

yes, it is.

now change the above line to a retrun statment, that should return the sum of your function pramaters.
then declare a sum variable using const keyword asign it the value caalling your function with two numbers as an argument.

7

Ok i used return to sum those two arguments. And then called sum variable outside function and changed arguments for 5 and 10.
It works now, thanks!

I forgot about return statement in JS :sweat_smile:
