JS one line code to obtain the maximum and minimum values of the array

   let dpartArr = [].concat(dpart1, dpart2, dpart3, dpart4, dpart5, dpart6, dpart7,);
   
   //  Get array maximum 
   let dpartArrMax = Math.max.apply(null, dpartArr);   
   //  Get the minimum value of the array 
   let dpartArrMin = Math.min.apply(null,dpartArr);
