modify your code to run in the IDE's Node.js environment. The output of your program running in the Node.js environment should be similar to Figure 1 (i.e. individually list each element of the given array). An added requirement is to sum up the values of the array elements and output that as well. Test your code with the following array: [8, 22, 40, 12, 2].

 

function arrayAverage(anArray){
     var sum = 0;
     for (i=0; i       sum = sum + anArray[i];
     }
     return sum/anArray.length;
   }
 function arrayLargest(anArray){
      var large = anArray[0];
 for(var i = 0; i < anArray.length; i++) {
  if(anArray[i] > large) {
   large = anArray[i];
  }
   }
 return large;
 }
 function isEven(anArray) {
  for(var i = 0; i < anArray.length; i++) {
  if(anArray[i] % 2 == 0) {
   return true;
  }
 }
 return false;
}
   
 function isAllEven(anArray) {
 var count = 0;
 for(var i = 0; i < anArray.length; i++) {
  if(anArray[i]%2 == 0) {
   count++;
  }
 }
 if(count == anArray.length) {
  return true;
 }
 else {
  return false;
 }
}
 function isContained(anArray, aString) {
 
 for(i = 0; i < anArray.length; i++) {
  for(var i=0;i       if(anArray[i] == aString)
         return true;
     }
   return false}
 
 }
