Am incercat sa aplic recursivitatea, dar am nevoie de alt output. De verificat cu tine la coaching.

function persistence(num) {
   if (String(num).length == 1) return num;
   return persistence(String(num).split('').reduce((acc,value)=> acc * value));
}

function persistence(num) {
  let output = 0;
  while(String(num).length > 1) {
   num = String(num).split('').reduce((acc,value)=> acc * value);
   output += 1;  
   }
  return output;
}

function persistence(num) {
  return String(num).length > 1 ? 1 + persistence(String(num).split('').reduce((acc,value)=> acc * value)) : 0;
}
