This is because posts is a JSON object and not an array that you can use the map() function with. Instead, you need to give the array to the map() function before you can pull out the titles.

To access the array of the JSON object, you can use posts['data'].

Changing the Target Framework to 4.8 should get you C# 7.3 features. C# features are standardized and correspond with the framework version.

You could do this:

You need to request the GUILD_MEMBERS when initiating your client otherwise this event will not be triggered.

Try change you api.js file like this

.aws/config had a subtle error - [profile default] isn't meaningful, so the two blocks should have been merged into [default]. Only the non-default profiles should have profile in the name.

You can do it by adding z-index to #navbar-container.
.videos is same level with #navbar-container, but there's no z-index property in #navbar-container, so it's behind the .videos element.
z-index to sublevel element doesn't work to super leveled elements.

Try:

This doesn't have anything to do with classes specifically but with how .bind works.

You have been on the right track. The most relevan section here is 9.4.1.2.

Just as a recap: ECMAScript distinguishes between two types of functions: callable functions and constructable functions. Function expressions/declarations are both, whereas e.g. class constructors are only constructable and arrow functions are only callable.

In the specification this is represented by function's internal [[Call]] and [[Construct]] methods.

new will trigger the invocation of the internal [[Construct]] method.

.bind will return a new function object with different implementations for [[Call]] and [[Construct]]. So what does the "bound" version of [[Construct]] look like?

9.4.1.2 [[Construct]] ( argumentsList, newTarget )

When the [[Construct]] internal method of a bound function exotic object, F that was created using the bind function is called with a list of arguments argumentsList and newTarget, the following steps are taken:

1. Let target be F.[[BoundTargetFunction]].
2. Assert: IsConstructor(target) is true.
3. Let boundArgs be F.[[BoundArguments]].
4. Let args be a new list containing the same values as the list boundArgs in the same order followed by the same values as the list argumentsList in the same order.
5. If SameValue(F, newTarget) is true, set newTarget to target.
6. Return ? Construct(target, args, newTarget).

What this means is that the bound constructor will "construct" the original function (F.[[BoundTargetFunction]]) with the bound arguments (F.[[BoundArguments]]) and the passed in arguments (argumentsList), but it completely ignores the bound this value (which would be F.[[BoundThis]]).

but are there other sorts of functions that are being fed something else than the value passed to bind() ?

Yes, arrow functions. Arrow functions do not have their own this binding (the value from the closest this providing environment is used instead), so bound arrow functions also ignore the bound this value.
