使用映射函数中的反应挂钩为变量赋值

Question

If you think this question is stupid, sorry for that and please forgive me because iam Beginner.:)

1) I want to declare variables using react hooks i done like this:

const[adata,setAdata]=useState(   
                    name:"",
                    companyname: ""
                  })

2)I want to assign " name" to the value(name=filteredperson.name,companyname=filteredperson.companyname) that inside map function here, map function code:

    {data.map((filteredPerson, index) => (
<td>{filteredperson.name}</td>
<td>{filteredperson.companyname}</td>

3)Finally,so i assigned my map function values to variables using react hooks, i want to print it on console.

for eg:name:{filteredperson.name} value in console

Note:filteredperson is a map function. I want to assign map values to variables that are using react hooks.

Answer 1

Your data variable is of type {name: string, companyname: string} , so to assign value to this variable, you call the setter function:

setData({name: NAME_VALUE, companyname: COMPANYNAME_VALUE})

After you set the value of this object, you can print the values with:

console.log(data.name) console.log(data.companyname)
