So I'm trying to learn about JavaScript and geolocation, but I've run into this, probably simple, problem:
let myLat; // Global
navigator.geolocation.getCurrentPosition((position) => {
myLat = position.coords.latitude;
console.log(myLat); // works
});
console.log(myLat); // undefined
I don't get why I cannot just use a global variable to hold the latitude-info?

I am attempting to access color options from a chrome extension, when I run this code, the second output is undefined, even though the variable is supposed to be able to be accessed by every part of the code because I defined it in the beginning.
var color;
function updateColor(){
chrome.storage.sync.get("favoriteColor", function(result) {
color = result.favoriteColor;
console.log(color);
});
console.log(color);
};
updateColor();
I have searched all over the internet and I am unable to come up with a solution, any help would be greatly appreciated :)

I have function like this:
function GetLala() {
var lala = $.getJSON(uriLala).done(function (data) {
return data;
});
return lala;
}
Then code like this:
var data = GetLala();
console.log(data.responseJSON);
This returned me undefined. If I type this code in google chrome console - then work.

I'm pretty confused by the JavaScript scoping. I have a call to FB.api (shown below) that I would like to return a response object:
(function() {
var permissions;
FB.api("/me/permissions", "get", {access_token: options.token}, function(r) {
permissions = r;
});
console.log(permissions);
})();
Ideally, I'd like to assign FB.api to a variable, and use the anonymous function to return the r component, but it appears like that's not doable.
Why is permissions undefined? Is there a way to set permissions in the parent scope?
