Or by passing filename as first argument.
```
$ fx data.json
```

Pipe into `fx` any JSON and anonymous function for reducing it.
```bash
$ curl ... | fx 'json => json.message'
```

Or same as above but short.
```bash
$ curl ... | fx this.message
$ curl ... | fx .message
```

Pass any numbers of arguments as code.
```bash
$ curl ... | fx 'json => json.message' 'json => json.filter(x => x.startsWith("a"))'
```

```bash
$ curl ... | fx '_.groupBy("commit.committer.name")' '_.mapValues(_.size)'
```

Update JSON using spread operator.
```bash
$ echo '{"count": 0}' | fx '{...this, count: 1}'
{
  "count": 1
}
```

Pretty print JSON with dot.
```bash
$ curl ... | fx .
```
