JSON Route is returning Empty

I am trying to scrape some info from a website and return it in an API. The object, RESULT, is being logged in the terminal, but when i go to /api/scrape, the JSON object is empty...

router.post("/api/scrape", function(req,res){
var result = [];

request("https://www.reddit.com/", function(error, response, html) {
// Load the body of the HTML into cheerio
    var $ = cheerio.load(html);
    // Empty array to save our scraped data

    // With cheerio, find each h4-tag with the class "headline-link"
    $(".entry").each(function(i, element) {
        // Save the text of the h4-tag as "title"
        var title = $(this).text();
        // Find the h4 tag's parent a-tag, and save it's href value as "link"
        var link = $(element).children("a").text();
        // For each h4-tag, make an object with data we scraped and push it to the result array
        result.push({
        title: title,
        link: link
        });
    });
    // After the program scans each h4.headline-link, log the result  
    console.log(result);
    return result;        
});
res.json(result);

})
