you can do something like that by using map function

const new_object = data.map(({ ID, calldate, callend, caller }) => {
    return { ID, calldate, callend, caller };
});

You can use class-transformer.

Create a class with all the properties you need
Convert plain (literal) objects to class (constructor) objects with proper options.

You can also look at the implementation of plainToClass and implement your own.
