Concatenation two data from two fetch in react native - react-native

Question

I am sorry for distributing you with stupid question,i have to make notification page ,where i know sender and notification's data,
but i cant concatenated sender and notification's data
let responseJson = await response.json();
console.log(responseJson)
if(responseJson.success){
// this.setState(this.state.data.sender=responseJson.data.sender)
responseJson.data.map(notificationInfo=>{
this.getData(notificationInfo.id,notificationInfo.sender)
})
}
else{
console.log("No notification")
}
Method getdata
..FETCH
const responseJson = await response.json();
this.setState({data:responseJson})
// console.log(responseJson.success)
if(typeof responseJson.success != "undefined"){
this.setState({
data=[...this.state.data,sender]
})
the best answer was like below:
Array [
Object {//sender
"name": "Admin Adminovich",
#someother data
},
Object {
"name": "Test Testovich",
#someother data
},
Object {
"name": "just4ina",
#someother data
},
but I need it like
data:[
Object {
"name": "Test Testovich",
"sender": Object {//sender
"name": "Admin Adminovich",
#someother data
},
Object {
"name": "Test",
"sender": Object {//sender
"name": "Admin Adminovich",
#someother data
},
]
ALL concatenation was not what i want
