loop array reverse

var array = [1,2,3,4];
//array stores a set of arguments, which in this case are all numbers

var totalArguments = array.length;
//totalArguments stores the total number of arguments that are in the array


//To get the arguments of the array to display in reverse we will -
// first have to subract 1 to totalArguments because to access the -
// arguments of an array they start from 0 to the total number of -
// arguments-1, which in this case would be totalArgumenst = 4  -
// 4 - 1 = 3 , so we are going to display 0 to 3 with a for loop

for (var i = totalArguments - 1 ; i >= 0 ; i--) {
console.log(array[i]);
}

JAVASCRIPT ARRRAY LOOP BACKWARDS

let reverseArray = Arr=>{
  let pushed =[];
  for(let i = Arr.length -1; i >= 0; i--){
     pushed.push(Arr[i]);

  return pushed
}



const sentence = ['sense.','make', 'all', 'will', 'This'];

 console.log(reverseArray(sentence)) 
// Should print ['This', 'will', 'all', 'make', 'sense.'];

array reverse with for loop

function reverseArray (arr) {
    var newArr = [];
    var inArr = arr;
    console.log(inArr);
    for (i = 0; i < arr.length; i++) {      
        newArr[i] = inArr.pop(i);       
    }   
    return newArr;
}
reverseArray(["A", "B", "C", "D", "E", "F"]);

// OUTPUT: ["F", "D", "E"]
