  for (var i = 0; i < list.length; i++) {
    action(list[i]);

var logItem = function (item) {

var listOfThings = ["soap", "candle", "deer", "wine", "bread"];

forEach(listOfThings, logItem);

forEach(anotherListOfThings, function (item) {
  console.log(item + "'s length is " + item.length);
});

//Great read so far.
//If you would like correct grammar replace the final forEach with:

forEach(anotherListOfThings, function (item) {
if(item[item.length-1]==="s"){
console.log(item + "' length is " + item.length);
}else{
console.log(item + "'s length is " + item.length);
}
});
