# 02. Optional Catch

The shorthand syntax for `catch` expression will be available in ES2018:

```javascript
try {
    ···
} catch {
    ···
}
```

There are two general reasons for omitting the `catch` binding:

* If you want to completely ignore the error.
* You don’t care about the error or you already know what it will be, but you do want to react to it.

```javascript
let jsonData;
try {
  jsonData = JSON.parse(str); // (A)
} catch {
  jsonData = DEFAULT_DATA;
}
```
