I'm using Leafler to create a map for a video game (Arma 3). I already created some markers and layers but now I would like to create a control panel to display or no the layers on my map.

Here is my code from the app.js. Could someone help me to find the right procedure to add the controll panel with checkboxes.

I made a very simple function that just prints the latest tweet from a given user:

I am creating an airport scene.

I want the tower to be drawn in back of Hangar, also planes inside hangar are also visible. If i move my eye point airplanes are also shown behind tower or hangar.. Also when i look up from below the surface objects are visible too..

Here is my code...

I have a large data frame that looks like this:

I am using gcp functions, and I think the function crush log is not informative like below, which only mention finished with status: 'crash'.

Wondering how we can get a crush stack log to find out the bug easier?

Thank you.

Good day, there is a client-server project, a client on the hangar, a server on the bark. On the server, the file download code:

I have the following code:

First of all, I'm a newbie at programming.

I have a button (Canciones) that creates multiple buttons in the empty div (to the right), but I can't add EventListeners to them, I cannot make it work. I think that maybe the Listeners are on, but they don't work 'cause they "can't read property of undefined". I don't understand what's happening, but I wasted a lot of time trying to solve it by myself.

I am using the Jest framework and am trying to implement a mock of a function. I have a small airport app that allows a user to takeoff and land planes but it must be restricted due to random weather.

The weather is in another class and is randomised, for my tests I need to mock the weather function to always return true on one test and false on others.

The difficulty I have is how exactly to implement the mock function? The docs talk of using jest.fn and setting it to a constant variable but this confuses me as I do not understand how jest.fn can equate to a function when it's not fed the function name. The further jest mock docs, while comprehensive, are a bit inaccessible to someone learning and most other resources I have are resulting in the same confusion. In essence I am hoping for a layman's terms guide to implementing this? Such as -

• how to correctly declare a function as mocked?
• how to explicitly declare the return value of that function?
• how to call that mock function within my test suite?
