how to run a for loop backwards code example

Example 1: Count Backwards With a For Loop

var myArray = [];
for (var i = 9; i > 0; i -= 2){
    myArray.push(i);
}
console.log(myArray); // console output [ 9, 7, 5, 3, 1 ]

Example 2: reverse for loop

for (int i = myArray.Length - 1; i >= 0; i--)  
{  
    // Do something ...  
}
