NodeJS regex returns 0 on string.search()

I'm working on a NodeJS script (launched from the CMD with the node command) getting me some HTML content in a string, in which I need to extract some data between a specific <div> element. I'm having a hard time firguring why this portion of code doesn't give me the desired output.

const input = '<div class="some_class">Some data</div><div class="some_other_class">< class="some_other_other_class">...</div></div>'
const regex = new RegExp(/<div class="some_class"\>(.*?)<\/div>/g)
let obj = {
    'tmp': input.search(regex),
}
console.log(obj) // outputs { tmp: 0}
console.log(input.search(/<div class="some_class"\>(.*?)<\/div>/g)) // outputs 0
 
const x = input.search(/<div class="some_class"\>(.*?)<\/div>/g)
console.log(x) // outputs 0

I know this seems a bit of a regular issue here, but I tried passing the Regex with string format (between single quotes '), passing it as a Regex (between delimiter /) and finally by defining a new RegExp element, but without success. I always happen to get 0 as an output.

However, when I test it on an online tool, it does match and capture the desired data in the group #1 : https://www.regextester.com/?fam=131034

I don't know if I'm missing something or if I'm doing something wrong, but after some hours spent on this issue, I'm quite struggling to get my ideas straight.

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".
