# Is "else" required?
|
|
|
|
The following function returns `true` if the parameter `age` is greater than `18`.
|
|
|
|
Otherwise it asks for a confirmation and returns its result:
|
|
|
|
```js
|
|
function checkAge(age) {
|
|
if (age > 18) {
|
|
return true;
|
|
*!*
|
|
} else {
|
|
// ...
|
|
return confirm('Did parents allow you?');
|
|
}
|
|
*/!*
|
|
}
|
|
```
|
|
|
|
Will the function work differently if `else` is removed?
|
|
|
|
```js
|
|
function checkAge(age) {
|
|
if (age > 18) {
|
|
return true;
|
|
}
|
|
*!*
|
|
// ...
|
|
return confirm('Did parents allow you?');
|
|
*/!*
|
|
}
|
|
```
|
|
|
|
Is there any difference in the bahavior of these two variants?
