I have a function wich reads some JSON data from a file an I want to return that data. This actually works right now, BUT when I log the global Variable USERS then on the first func call it's undefined and on the second call I get the right value. Does somebody know why ?

My Function:

async function readJson() {
fs.readFile('./src/users.json', 'utf-8', (err, data) => {
    if (err) {
        console.error(`Fehler: ${err}`)
    } else {
        USERS = JSON.parse(data)
    }
})
   return USERS
}

Thanks for all answers
