Return(value); not working in function

Question

When I call This function:

function getweb(addr){
    request(addr, function (err, response, body) {
    let artlatestjson = JSON.parse(body);
    aart = artlatestjson.title;
    alink = artlatestjson.url;
    ascore = "｜  Score " + artlatestjson.score;
    return(aart)
  });
}

With:

console.log(getweb(jsonfileaddres))

(jsonfileaddres being url of the json file)

It allways returns undefined, even though aart is set to the corect thing.
