8.3 Reverse Array.js

var myArray = [1, 2, 3, 4];
reverse(myArray);
console.log(myArray) // [4, 3, 2, 1]

function reverse(arr){
  var cloneArray=arr.slice();
  var tmpArray=[];
  for(var i=0;i<arr.length;i++){
    tmpArray.push(cloneArray.pop());
  }
  myArray=tmpArray.slice();
}

/* SCHOOL SOLUTION

function reverse(arr) {
  var midPoint = Math.floor(arr.length/2);
  console.log(midPoint)
  for (var i=0; i<midPoint; i++) {
    var temp = arr[i];
    arr[i] = arr[(arr.length-1)-i];
    arr[(arr.length-1)-i] = temp;
  }
}
