# Finally or just the code?
|
|
|
|
Compare the two code fragments.
|
|
|
|
1. The first one uses `finally` to execute the code after `try..catch`:
|
|
|
|
```js
|
|
try {
|
|
work work
|
|
} catch (e) {
|
|
handle errors
|
|
} finally {
|
|
*!*
|
|
cleanup the working space
|
|
*/!*
|
|
}
|
|
```
|
|
2. The second fragment puts the cleaning right after `try..catch`:
|
|
|
|
```js
|
|
try {
|
|
work work
|
|
} catch (e) {
|
|
handle errors
|
|
}
|
|
|
|
*!*
|
|
cleanup the working space
|
|
*/!*
|
|
```
|
|
|
|
We definitely need the cleanup after the work, doesn't matter if there was an error or not.
|
|
|
|
Is there an advantage here in using `finally` or both code fragments are equal? If there is such an advantage, then give an example when it matters.
