boucle de tableau inversée

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]);
