Answer 2

On line 7 You wrote:
resolve(add((multiply(5,6),10)));

That is actually one more pair of () than what You need. It should like this:
resolve(add(multiply(5,6),10));
And then Your output should be 40.

Furthermore I recommend formatting Your code better. Use spaces after commas, spaces after the "=>" and either use semicolons or don't.

Answer 3

There is more "()" than needed in your line 7

Answer 5

@Sanja Panic , what I meant is that the system says there is error in line 1(Promise). Of course I expect to see the reject value passed as the argument to the .catch()

okafor okwuchukwu charisma you check arr.length to be bigger than 5, but arr.length is 3. So this will show your reject code
