Friends or Foes?

Friends or Foes?

// 12/22/2015
// Make a program that filters a list of strings and returns a list 
// with only your friends name in it. All your friends only have 
// four letter in their name.

// Ex: Input = ["Ryan", "Kieran", "Jason", "Yous"], 
// Output = ["Ryan", "Yous"]

// My Solution:

function friend(friends){
  var arr2=[];
  arr2=friends.filter(function(element){
      return element.length==4
  })
 return arr2;
}

friend(["Ryan", "Jimmy", "123", "4", "Cool Man"])
//friend(["Ryan", "Kieran", "Mark"])




// function friend(friends){
//   var arr1=[];
   
//   for(var i=0;i<=friends.length-1;i++){
//       if(friends[i].length==4){
//           arr1.push(friends[i])
//       }
//   }
//   return arr1;
  
// }
