how to conditionally update data field with axios - react-native

Question

i have screen when user have buttons to change hes Name, or phone
i have function that handle if the user clicked on change name or phone
now i want to conditionally implement a PUT req, that change only the field that the user clicked,
for example look what exactly i want to do: (look at the if)
how can i do that conditinally field?
const updateUser = dispatch => async (userId, param, value, token) => {
dispatch({ type: "loading", payload: true });
try {
const res = await indexApi.put(
`/user/${userId}`,
{
if(param==="name") name: value,///////////////here
if(param==="phone")phone: value ////////////here
},
{
headers: {
Authorization: `Bearer ${token}`,
},
}
);
note that i also tried to do :
name: (param===name) ? value: res.data.user.name
phone: (param===phone) ? value: res.data.user.phone
I mean take the data from the server , but the server does not return me and sends me an UNDEFINED comment res.data.user.name undefined................
probably its not enough to get it until the func finish or something

Answer 1

if you want to do object with specified property name try this:
{
[param]: value
}
In brackets value of variable param become 'name' or 'phone' in your case.
const updateUser = dispatch => async (userId, param, value, token) => {
dispatch({ type: "loading", payload: true });
try {
const res = await indexApi.put(
`/user/${userId}`,
{
[param]: value
},
{
headers: {
Authorization: `Bearer ${token}`,
},
}
);
