    There are two options:

    1.

    let name = arr.name
arr = {...arr, name: null, newname:name}

    You can use omit function from lodash library, and this option is better. Here is docimentation of omit function

    let arr={name:'ash', id:2}

let newname = arr.name;
delete arr.name

arr['newname'] = newname

console.log(arr)

    You can use a variable to store the value of name ,then use Object operator delete the key of name
