Timeline | turn text files into an HTMLJS timeline

I have an array for a timeline chart of Google Charts

So the array looks like follows

I have a program that shows a slideshow of pictures. When the picture is shown on the screen, I have this logged to the console. So, we then have the this object printed to the console: Photo of entire this object printed to console

I want to access and print the stimulus property to the console, however when I try to console.log(this.stimulus), I get TypeError: Cannot read property stimulus of undefined. Why can I not access this property?

EDIT: Forgot to add the misbehaving code:

I have a self updating list of orders that is scrollable. This is the parent component, where list is updated on a timer of 2 minutes, setup like so:

I have spent some hours playing with Electron and I have observed that it consistently takes more than 2.5 seconds to draw a trivial html file to the screen. The timeline is roughly as follows:

• 60 ms: app ready event is triggered; we create a window using new BrowserWindow()
• 170 ms: a blank window appears on the screen
• 2800 ms: the window shows the specified HTML

I have set up a repository with my code, which is derived from Electron's quick start docs.

Regarding my machine, I am running Windows 10 on a ThinkPad T460 from 2016 with a SSD and enough memory.

Shipping an application that shows a blank window for so long upon startup is a no-go for me. I assume most people developing Electron apps think similarly. Hence my first question: am I doing something wrong? Or is this the expected loading time for a trivial Electron app?

Assuming this is normal behavior, what is the common way to deal with this problem? Some ideas come to mind:

1. Asking Electron to show a splash screen: unless there is specific built-in functionality for this, it seems like a no-go, since the splash screen itself would be shown only after 2.5 seconds.
2. Hide the app's window until it is rendered (using the ready-to-show event), so no blank window is shown. This isn't ideal, since it means that the user doesn't get any feedback whatsoever that the application is actually loading.
3. Create a wrapper application (using native code) that displays a splash screen, launches electron and hides itself once the electron window is shown. Kind of defeats the purpose of using Electron in the first place, because you end up writing native code and adding accidental complexity.
4. Setting the background color of the window to something resembling your app, as suggested by the docs. This just doesn't look very well.

Given this must be a common problem, I hope standard solutions have been found by the community. I'd be glad if someone can point me in the right direction.

I need to build something like in the following:

This is the structure I built so far:

But I have difficult times to build the grid.

This is the code:

I have a Nuxt-based gsap (greensock) animation, where I'm trying to start that animation only when an audio track that I'm loading is available.

The HTML for the audio:

I recover thanks to an API a json file made up like this :

I make a graph with NextJs and ChartJs on the stats of the covid (over the last 30 days) that I get with an API that provides me with the date and the stats :

I have a JS function that works with a button; basically, it's supposed to show the HTML code after clicking the button. However, for some reason, when I load the page, the HTML is visible before clicking the button; clicking the button once makes the code disappear, and then clicking it again makes the code re-appear. It seems like the function is doing the opposite of what I want it to do, but I have no idea why it's doing this: comparing my code to other code that does what I want it to do, I don't see any visible differences.

Here is the script:
