move function out of jsx

Sorry in advance if this question seems inappropriate. Just tell me, I'll explain everything.

So my question is I would like to move the function (code below) from jsx and wrap it in useCallback. Since at the moment a new function is created for each element on each render.

......
{suggestedTags.length ? (
          <div className={classes.tagSuggestionWrapper}>
            {suggestedTags.map((tag) => {
              return (<div key={tag} 
                          className={classes.tagSuggestion} 
                          onClick={() => { selectTag(tag) }}>{tag}</div>
                          );            
            })}
          </div>
        ) : null }
......

Whole code

    export default function TagsInput(props) {
    const {tags, setTags, tagSuggestions} = props;
    const [input, setInput] = useState("");
    const [suggestedTags, setSuggestedTags] = useState([]);
    const [isValid, setIsValid] = useState(true);
  
    const onChange = (e) => {};

    const onSubmit = (e) => {};

    const onKeyDown = (e) => {};
  
    const deleteTag = (index) => {}

    return (
      <div className={classes.container}>
        {tags.map((tag, index) => <div className={classes.tag} key={tag}>
            {tag}
          </div>
        )}

        <input
          className={classes.input}
          value={input}
          placeholder={props.inputPlaceholder}
          onKeyDown={onKeyDown}
          onChange={onChange}
          maxlength={3}
          type="text" 
          minlength="3"
          onSubmit={onSubmit}
        />

        {suggestedTags.length ? (
              <div className={classes.tagSuggestionWrapper}>
                {suggestedTags.map((tag) => {
                  return (<div key={tag} 
                              className={classes.tagSuggestion} 
                              onClick={() => { selectTag(tag) }}>{tag}</div>
                              );            
                })}
              </div>
            ) : null }

      </div>
    );
  }

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 ...
