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"))' 
```

Access all lodash (or ramda, etc) methods by using [.fxrc](https://github.com/antonmedv/fx/blob/master/docs.md#using-fxrc) file.
```bash
$ curl ... | fx '_.groupBy("commit.committer.name")' '_.mapValues(_.size)'
```

Update JSON using spread operator.

}
```
