just having fun with array

arrayManipulation.js

function arrayManipulation(arr, command, location, value) {
  if(command == "remove" && location =="end") {
   
    return   arr.pop();
  } else if (command =="remove" && location =="beginning") {
 
    return     arr.shift();
  } else if(command ="add" && location =="beginning") {
    arr.unshift(value)
    return  arr
  }else if(command ="add" && location=="end") {
     arr.push(value);
    return arr
  }
}
