function question4(angka){
var w=0 , jml=0, rtt=0;
var nilai;
nilai=angka;


for(w=0;w < nilai.length;w  )
{
jml=jml nilai[w];
}
rtt=jml/nilai.length;
console.log(rtt);
}

console.log(question4([4, 5, 6, 7, 8]));
console.log(question4([100, 200, 300, 400, 500]));
console.log(question4([-1, 4, 7, 11]));

If there is one or more array elements with negative values, then the function is direct outputs the text 'Negative!'.

CodePudding user response：

First of all you don't have to call the question4() within a console.log() because the question4() doesn't return anything, instead check in the loop if (nilai[w] < 0) console.log('Negative!')

CodePudding user response：

it is so easy, question4 function must return a value..

    function question4(angka){
        for(w=0;w < angka.length;w  )
        {
          if(angka[w]<0)
            {
              return "Negative";
            }
        }

  return "Posetive";

}

Maybe you can use this

function hasArrayNegativeValue(valueArray){

for(i=0;i < valueArray.length;i  )
   {
     if(valueArray[i] < 0){
       return 'Negative';
      
       }
       
   }
  return null;
}

console.log(hasArrayNegativeValue([4, 5, 6, 7, 8]));
console.log(hasArrayNegativeValue([100, 200, 300, 400, 500]));
console.log(hasArrayNegativeValue([-1, 4, 7, 11]));

CodePudding user response：

You can use built in array method .some().

const hasNegative = [-1, 4, 7, 11].some(elem => elem < 0);

The result will be true, because this array contains element which is less than 0.

const result = hasNegative ? 'Negative' : 'Positive';

You can also put this logic into function and return result instead of assigning it to variable.
