Question

How can we improve the following program?
function main() {
move();
move();
move();
move();
move();
move();
move();
move();
move();
}

main();
JavaScript

A. Break down this program into more functions

B. Use a for loop to repeat the move command

C. Use a while loop to repeat the move command

D. Fix the indentation of this program

Answer 1

To improve the program you provided, option **B. Use a for loop to repeat the move command** is the best choice. This makes the code more concise and easier to read.

Here's how you could implement the improvement:

```javascript
function main() {
for (let i = 0; i < 9; i++) {
move();
}
}

main();
```

This revised version maintains the same functionality as the original but reduces redundancy by utilizing a loop, making it cleaner and easier to maintain.

While other options like breaking down into more functions (option A) or using a while loop (option C) are valid improvements, they may not be as straightforward for this specific scenario. Fixing indentation (option D) is a good programming practice, but it does not fundamentally improve the functionality or clarity of the program.
