vue.js - How can I modify json response and save it in state?

So for example, my json response looks like:

"name": "John"
"value": "5"

Then I pass it to my state

commit("SET_USER", response.data.user);

But, if name is == "John" i want the value to be 10 and pass it to mutation. Is it possible to do this? I can access value like this response.data.user[0].value

if(response.data.user[0].name == "John") {
              response.data.user[0].value == "10"
            }
            commit("SET_USER", response.data.users); // <-- state.cards
          })

You could use map function :

commit("SET_USER", response.data.user.map(item=>{
           if(item.name=='John'){
              item.value=10
           }
    return item;
}));

if you already know the index :

let users=response.data.user;
if(users[0].name == "John") {
              users[0].value = 10
            }
commit("SET_USER", users);
