How to initialize object property with async function?

Question

JavaScript

let data = new  function(){
        (async ()=> {
            return new Promise(resolve => {
                    ipcRenderer.send('message', 'ping');
                    ipcRenderer.on('reply', (event, arg) => {
                        resolve(arg);
                    })
            })
        });
    }

    let obj = {
        data: data
    }
    console.log(obj)

Answer 1

There can be several approaches here
: 1. make a factor that will asynchronously return an object initialized with data
2. make an init function in the object that will work asynchronously and return an initialized object.
3. surely there is something else....
