NodeJs javascript: wait until the previous object property is assigned before assigning the next property

Suppose I have code like this:

let result = {
  name: downloadNameFromInternetVerySlow(),
  isFamous: determineIfNameIsFamous(this.name);
}

const downloadNameFromInternetVerySlow = () => {
    path = "/home";
    const folders = fs.readdirSync(path).filter(file => fs.lstatSync(path).isDirectory());
    console.log(folders);
    return folders[0];
}

downloadNameFromInternetVerySlow can take a long time, meanwhile determineIfNameIsFamous depends on downloadNameFromInternetVerySlow‘s result to return correct value.

How do I make sure determineIfNameIsFamous only runs after downloadNameFromInternetVerySlow is done?

>Solution :

The code you show is entirely synchronous so asynchronous results aren’t actually the issue here like people were guessing. The issue is that this.name cannot be used to refer to a prior property in an object literal definition for several reasons, not the least of which this isn’t set to the object you want.

Instead, you can do this:

let result = {};
result.name = downloadNameFromInternetVerySlow();
result.isFamous = determineIfNameIsFamous(result.name);
