For some reason my variable isn't being stored when leaving the scope in the if statement. Code is below. I am pretty new to javascript, so I am a little unsure if it's a small fix?

            var address = document.getElementById('address').value;
            var lng = '';
            geocoder.geocode({'address': address}, function(results, status) {
              if (status === 'OK') {
                lng = ''+results[0].geometry.location.lng();
                alert(lng); // prints out the lng()
              }
            })

            alert(lng); // prints out blank

define your variable `lng` outside the function body – Hyyan Abo Fakher Feb 11 '18 at 16:44

@HyyanAboFakher That is already the case. – melpomene Feb 11 '18 at 16:45
var lng; outside of function – Mahdi Younesi Feb 11 '18 at 16:46
Sorry @HyyanAboFakher, that was a typo :( – ofarooq Feb 11 '18 at 16:46

To anyone suggesting defining the variable somewhere else: it's not the problem, and it won't help. Read the duplicate. – JJJ Feb 11 '18 at 16:47
It is because you are using an asynchronous function – Arun P Johny Feb 11 '18 at 16:47
The duplicate is really helpful, still trying to read the whole answer and trying to understand it though loll – ofarooq Feb 11 '18 at 16:47
The variable assignment happens after the alert is executed – Arun P Johny Feb 11 '18 at 16:48
