Question

function start(){
safePutBall();
move();
}
function safePutBall(){
if(noBallsPresent()){
putBall();
}
}
add a main function

Answer 1

Certainly! You can create a `main` function to kick off the execution of your program. Here’s how you can structure it:

```javascript
function main() {
start();
}

// The existing functions
function start() {
safePutBall();
move();
}

function safePutBall() {
if (noBallsPresent()) {
putBall();
}
}

// Dummy implementations of additional functions for context
function noBallsPresent() {
// Logic to check if no balls are present
return true; // Example: returns true for demonstration
}

function putBall() {
// Logic to put a ball
console.log("Ball put successfully!");
}

function move() {
// Logic to move
console.log("Moving...");
}

// Start the program by calling the main function
main();
```

### Explanation:
- The `main` function serves as the entry point of the program. When executed, it calls the `start` function.
- The `start` function executes the `safePutBall` function and then calls the `move` function.
- Dummy implementations for `noBallsPresent()`, `putBall()`, and `move()` are provided for context, but you would replace those with actual logic as needed in your application.
- Finally, `main()` is called at the end to kick off the entire process.
