```javascript
function checkEcoStandard(product) {
if (product.ecoStandard == 'high') {
console.log('The product meets our high eco-standard.');
} else {
console.log('The product does not meet our high eco-standard.');
}
}
```
在此例中,產品的環(huán)保標準等于'high',則打印條消息表示該產品達到了我司的高環(huán)保標準。否則,打印條消息表示產品沒有達到這個標準。
```javascript
function confirmDelivery(deliveryStatus) {
if (deliveryStatus == 'delivered') {
console.log('The delivery has been confirmed as delivered.');
} else {
console.log('The delivery is still in progress.');
}
}
```
