React jquery .toggleClass() does only work after compiler reloading

I´m trying to build this sideboard for my react application: https://codepen.io/illnino/pen/nwPBrQ . Anyways, I ran into a problem and I´m not able to solve this on my own.

So what is my exact problem ?

This code does NOT work if I try to hover on the sideboard icon as it should. After refreshing the page manually, it doesnt work either. But I noticed, if my react compiler reloads this application (after any change in my file) and I DON'T refresh the page manually, it works.

So .toggleClass() does only work, after my compiler reloads the code. After reloading the page on my own, it doesnt work again.

My Code

My css code is exact the same as on codepen. Of course the javascript and the html code are in the same file. The html code is also the same, so I´ll only give you my JS code (In fact I´m using typescript, but that shouldn't matter):

React.useEffect(() => {
    $(".gn-icon-menu").hover(function () {
        let e = $(".gn-menu-wrapper")
        e.toggleClass("gn-open-part")
      });
  
      $(".gn-menu-wrapper").hover(function () {
        $(this).toggleClass("gn-open-all")
      });
  }, []);

What have I tried ?

I really dont know, what to try. I´ll hope somebody maybe has a clue, what the error could be...

Where and how is this Laravel kernel constructor called? [closed]

Where and how is this Laravel kernel constructor called? public fucntion __construct(Application $app, $Router $roouter) { } I have read the documentation and some online tutorial but I can find any clear explanation. I am learning Laravel and I am wondering where does this kernel constructor receives its arguments from. "POSTMOTERM" CLARIFICATION: Here is more clarity.I have checked the boostrap/app.php and it is only used for boostrapping the interfaces into the container class. What is not clear to me is where and how the Kernel class is instatiated and the arguments passed to the object calling the constructor.Something similar to; obj = new kernel(arg1,arg2) or, is the framework using some magic functions somewhere? Special gratitude to those who burn their eyeballs and brain cells on this trivia before it goes into a full blown menopause alias "MARKED AS DUPLICATE". To some of the itchy-finger keyboard warriors, a.k.a The mods,because I believe in th...

Confusion between commands.Bot and discord.Client | Which one should I use?

Whenever you look at YouTube tutorials or code from this website there is a real variation. Some developers use client = discord.Client(intents=intents) while the others use bot = commands.Bot(command_prefix="something", intents=intents) . Now I know slightly about the difference but I get errors from different places from my code when I use either of them and its confusing. Especially since there has a few changes over the years in discord.py it is hard to find the real difference. I tried sticking to discord.Client then I found that there are more features in commands.Bot . Then I found errors when using commands.Bot . An example of this is: When I try to use commands.Bot client = commands.Bot(command_prefix=">",intents=intents) async def load(): for filename in os.listdir("./Cogs"): if filename.endswith(".py"): client.load_extension(f"Cogs.{filename[:-3]}") The above doesnt giveany response from my Cogs ...
