React setState one array with all objects

How can I get this.setState to update my state with one array and all my objects in that one array?

componentWillMount() {
let name = axios.get(“https://fcctop100.herokuapp.com/api/fccusers/top/recent”)
.then((data) => {
let camper = data.data.map((camp) => {
this.setState({fccCampers: camp})
})

})

}
