Question

How can we improve the following program?

function main() {
move();
move();
move();
move();
move();
move();
move();
move();
move();
}

main();
JavaScript


Break down this program into more functions


Use a for loop to repeat the move command


Use a while loop to repeat the move command


Fix the indentation of this program

Answer 1

Certainly! Let's improve the program step by step according to your requests.

1. **Break down the program into more functions:** We can create a separate function for moving, which can help make the code more modular and readable.

2. **Use a for loop to repeat the move command:** Instead of calling the `move()` function multiple times, we can use a for loop.

3. **Use a while loop to repeat the move command:** Additionally, we can demonstrate how to achieve the same result using a while loop.

4. **Fix the indentation of the program:** We’ll ensure the indentation is consistent and improves the readability of the code.

Here's the modified program with these improvements:

```javascript
function move() {
// Logic to move
console.log("Moving..."); // Just for demonstration purposes
}

function moveMultipleTimes(times) {
for (let i = 0; i < times; i++) {
move();
}
}

function moveWithWhile(times) {
let count = 0;
while (count < times) {
move();
count++;
}
}

function main() {
const times = 8;

moveMultipleTimes(times); // Using for loop
console.log("Moved using for loop.");

moveWithWhile(times); // Using while loop
console.log("Moved using while loop.");
}

main();
```

### Summary of Changes:
- We added a `move()` function to encapsulate the move logic.
- We created the `moveMultipleTimes()` function that uses a for loop to execute the `move` function the specified number of times.
- We added the `moveWithWhile()` function that uses a while loop to do the same task.
- The `main()` function now calls both methods and includes some console outputs to make the functionality clear.
- Overall indentation and structure were enhanced to make the code clearer and easier to read.
