Writing to a variable?

Question

JavaScript

Hello.

There are 2 functions:

const getFile = async ()=>{
  return await fs.readFile('file')
  .then(data=>{ return data });
};

const getFileFunc = async ()=>{
  const file =  await getFile();
  console.log(file); //выводит прочитанный файл
  return file;
};

And I would like to write the result of getFileFunc to a global variable, but since node works asynchronously,

const file = getFileFunc();

you can’t do it simply, because this will return the promise in the pending status.

Can you please tell me if there is any way to write the result of getFileFunc to a global variable?

PS the fs module on promises is connected
