title: JavaScript Promises Finally
|
|
---
|
|
|
|
# Introduction
|
|
|
|
Like [Exceptions](20201111094033-javascript_exceptions_finally), since
|
|
[ES2018](20201030095105-es2018) JavaScript
|
|
[Promises](20200911154351-promises) also support `.finally()`.
|
|
|
|
# Syntax
|
|
|
|
``` javascript
|
|
promise
|
|
.then((result) => {})
|
|
.catch((error) => {})
|
|
.finally(() => {});
|
|
```
|
|
|
|
## Shorthand
|
|
|
|
``` javascript
|
|
promise.finally(() => {});
|
|
```
|
|
|
|
is equal to
|
|
|
|
``` javascript
|
|
promise.then(
|
|
(result) => {
|
|
return result;
|
|
},
|
|
(error) => {
|
|
throw error;
|
|
}
|
|
);
|
|
```
