Tell us what’s happening:
Output is correct when test locally but code is not passing FCC

  **Your code so far**


let c=new Array();
function largestOfFour(arr) {
  arr.map(a=>{
      let b=Math.max(...a);
     
      c.push(b);
    
  
  });
  return c;
}

largestOfFour([[4, 5, 1, 3], [13, 27, 18, 26], [32, 35, 37, 39], [1000, 1001, 857, 1]]);

Challenge: Return Largest Numbers in Arrays

Link to the challenge:

#2 
const one = largestOfFour([[4, 5, 1, 3], [13, 27, 18, 26], [32, 35, 37, 39], [1000, 1001, 857, 1]]);
const two = largestOfFour([[4, 5, 1, 3], [13, 27, 18, 26], [32, 35, 37, 39], [1000, 1001, 857, 1]]);
console.log(two);

What gets logged?

Hi Dan,
Thank you for your response. I am getting this output

     5,   27, 39,
  1001,    5, 27,
    39, 1001
]

and is it the right output?

do you understand why you get it?

Hi Ilenia,
Ohh, Its outputting double values which is wrong.

Hi,
Thank you everyone for your help. You helped me to question further about my code. I resolved it. Below is the updated code.


function largestOfFour(arr) {
  let c=new Array();// I added the array now in function 
    arr.map(a=>{
        let b=Math.max(...a);
       
        c.push(b);
      
    
    });
    return c;
  }
  
  largestOfFour([[4, 5, 1, 3], [13, 27, 18, 26], [32, 35, 37, 39], [1000, 1001, 857, 1]]);
