How to correctly use enter/update/exit pattern for flexbox I've created w/ d3.js?

I've created a flexbox w/ d3, and want to be able to search and sort it. I got search and sort working separately-- see here: https://jsfiddle.net/yx4o0gj8/1/ -- but not together.

I got help on the sorting via the last question I posted on Stack Overflow, and it was noted that I wasn't using the enter/edit/update pattern for d3. That's why search and sort don't work together.

I've tried moving to the enter/update/exit pattern, but I'm missing something. Now the data doesn't show up at all. I've looked at examples, but they are mostly showing charts where there is a .transition().duration() attribute added. I'm not sure what the equivalent 'update' portion would be here.

        data = [
            {
                "name": "Dave",
                "dept": "Marketing",
                "region": "South",
                "items": 28
            },
            {
                "name": "Amy",
                "dept": "IT",
                "region": "West",
                "items": 46
            },
            {
                "name": "John",
                "dept": "Sales",
                "region": "North",
                "items": 35
            },
            {
                "name": "Sarah",
                "dept": "Communications",
                "region": "North",
                "items": 13
            }
        ]

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 ...

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".
