How can you count the number of items in the array - what do you have to add to this code?
<!DOCTYPE html>
<html>
<body>
<p>Click the button to sort the array.</p>
<button onclick="myFunction()">Try it</button>
<p id="demo"></p>
<script>
var fruits = ["Banana", "Orange", "Apple", "Mango"];
document.getElementById("demo").innerHTML = fruits;
function myFunction() {
fruits.sort();
document.getElementById("demo").innerHTML = fruits;
}
</script>
</body>
</html>
Many thanks
To count the number of items in the array, you can add the following line of code to the `myFunction()` function:
```javascript
var count = fruits.length;
```
This will calculate the number of elements in the `fruits` array and store it in the `count` variable. You can then use this variable to display the count on the webpage.
Here's the modified code:
```html
<!DOCTYPE html>
<html>
<body>
<p>Click the button to sort the array.</p>
<button onclick="myFunction()">Try it</button>
<p id="demo"></p>
<script>
var fruits = ["Banana", "Orange", "Apple", "Mango"];
document.getElementById("demo").innerHTML = fruits;
function myFunction() {
fruits.sort();
var count = fruits.length;
document.getElementById("demo").innerHTML = "Count: " + count + "<br>" + fruits;
}
</script>
</body>
</html>
```
After clicking the "Try it" button, you will see the sorted array and the count displayed below it.
