# Declarative State & Side-effect management with [CerebralJS](https://cerebraljs.com/)
|
|
|
|
Use [CerebralJS](https://cerebraljs.com/) to manage an apps state and side effects in a declarative manner:
|
|
|
|
Declarative CerebralJS:
|
|
|
|
```js
|
|
;[
|
|
setLoading(true),
|
|
getUser,
|
|
{
|
|
success: setUser,
|
|
error: setError,
|
|
},
|
|
setLoading(false),
|
|
]
|
|
```
|
|
|
|
vs imperative JS:
|
|
|
|
```js
|
|
function getUser() {
|
|
this.isLoading = true
|
|
ajax
|
|
.get('/user')
|
|
.then(user => {
|
|
this.data = user
|
|
this.isLoading = false
|
|
})
|
|
.catch(error => {
|
|
this.error = error
|
|
this.isLoading = false
|
|
})
|
|
}
|
|
```
|
