React Router v6 - re-rerenders

I am trying to use react router v6 for my application. Whenever I try to navigate from a component programmatically using useNavigate() hook, the entire component gets re-rendered when I navigate. I am trying to build a header which navigates between different pages.

I want to avoid unwanted re-renders of the header component as the routing is taking place only on the children. However if I move the Button component to a separate component and use the useNavigate hook within that child component, the header component is restricted from re-renders. How ever the button component gets re-rendered. I would like to understand how this useNavigate() hook is designed and how should we properly use it to avoid these situations.

Thanks in advance!

export default function Header() {
    console.log("header rendering...")
    const navigate = useNavigate()
    return (
        <>
            {
MENUS.map((menu, index) => {
                    return <Button 
                              key={index} 
                              onClick={() => navigate(menu.route)}
                            >
                            {menu.name}
                            </Button>
              })
            }
        </>
    );
}

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 ...
