Write some code to print an array in reverse order.
let arr = [4, 5, 6, 7]
Here's an example of a JavaScript code that prints an array in reverse order:

```javascript
let arr = [4, 5, 6, 7];
for (let i = arr.length - 1; i >= 0; i--) {
  console.log(arr[i]);
}
```
This code iterates over the array starting from its last element and goes backward, printing each element as it goes.
