Necessity checking if video exists or not

export const addComment = asyncHandler(async (req, res) => {
    const { videoId } = req.params;

    if (!isValidObjectId(videoId)) {
        throw new ApiError(400, "Invalid video id");
    }

    const { content } = req.body;

    if (!content) {
        throw new ApiError(400, "Content is required");
    }

    const comment = await Comment.create({
        content,
        owner: req.user?._id,
        video: videoId
    })

    if (!comment) {
        throw new ApiError(500, "Comment creation failure");
    }

    return res.status(200).json(new ApiResponse(200, comment, "Comment created"))
})

export const addComment = asyncHandler(async (req, res) => {
    const { videoId } = req.params;

    if (!isValidObjectId(videoId)) {
        throw new ApiError(400, "Invalid video id");
    }

    const { content } = req.body;

    if (!content) {
        throw new ApiError(400, "Content is required");
    }

    const comment = await Comment.create({
        content,
        owner: req.user?._id,
        video: videoId
    })

    if (!comment) {
        throw new ApiError(500, "Comment creation failure");
    }

    return res.status(200).json(new ApiResponse(200, comment, "Comment created"))
})

here I am making a add comment to video controller i am fetching the video id (mongoDB id) from url param and user id from req.user (a custom middleware is responsible to check if user is logged in or not and if so adds the user to req object) then if video id is valid mongo id and comment content exists I am creating a new comment doc. Now my question is i am not checking if a video with that ID already exists or not, so Should I do a query for that or do i not have to since user will have to click a video in order to be able to comment on it

Using JS to redirect instead of anchor tag

function setCard(){
    const main = document.querySelector("main");

    for(let i = 0; i < projectData.length; i++){
        const card = makeCard(projectData[i].title);
        main.appendChild(card);

        card.addEventListener("click", () => {
            localStorage.setItem("id", projectData[i].id);            
        })
    }
}

function setCard(){
    const main = document.querySelector("main");

    for(let i = 0; i < projectData.length; i++){
        const card = makeCard(projectData[i].title);
        main.appendChild(card);

        card.addEventListener("click", () => {
            localStorage.setItem("id", projectData[i].id);            
        })
    }
}

The makeCard() basically returns a div thats wrapped in an anchor tag. And I am adding click event listener to all the anchor tags cause i have to store the id in local storage of the card that has been clicked . This works but idk why something feels sketchy about this to me. Idk what. Does this approach have any drawback?

What does the backend server listens to??

when u make backend, does your server listen to your pages URL?? that is when u say host your webpage, it is hosted on a url. does the the back listen to THAT url? or the localhost of the machine that hosts the site? The little so knowledge i have about backend thus far, FR and BE communicate with eachother via API. But the question i asked above, this occurred to me when I was thinking about how when u click a link, it redirects user to a certain route.. Now there 2 possible ways that can be done as far as I can think of

We just simply use anchor tags or js with location.href to simply add that route to the Link and redirect. As user lands on that page, static elements r rendered and dynamics infos r fetched using API from the backend and later rendered. In this case i suppose the server can just listen to the machines localhost??

2ndly, server listens to the users location and based on where user is server does it's stuff..

Now idk if 2nd one is even a legit way to do it . but these r the 2 possibilities i can think of. Thanks!

req.body returns undefined

haya!!. So today i was thinking of trying out backend. and i installed express and nodemon and started working on it. everything seemed to be working fine until I made a form in my html and tried to receive and log data in my server.js. But it seems like req.body always returns undefined . I know the server and client side is working fine cause when I submit, it gives my the error I coded in the server.post(). That means i am indeed sending post req to my server . Here is the github code the code: https://github.com/glutonium69/Codespace_1/

Confusion with SCSS

in the video that i added, u can see i have made a utilities folder for styling purpose where i have 2 files reset.scc which is for css reset and variables.scss which is fro global variable now they r imported in my App.scss i didn't install any scss pkg using npm, only a live scss compiler, beforehand when i made App.scss and started the live compiler it made 2 files App.css and App.map.css and my compiled code gets imported in App.css now after making the utility files when i started the compiler, it made both .css and .map.css for each of my scss file and compiled the code in their respective .css file but since i had them @imported './path' in my App.scss as well, the compiled code of my utility files are also in my App.css so now i am confused about what to do. I thought it was supposed to only make a css file for my App.scss and as other scss files will be imported here it'll compile all of them into one App.css file So my question is, am i getting it wrong or is it supposed to not work like it is rn? tnx ❤️

can clamp() be used for anything other than font-size

well I know what clamp() function is or what it does I've only seen people using it for font-size but i wanna know if it is possible to use it anything else for example, margin, padding or gaps I also know about min() max() functions that we can use but i once used clamp() for gaps and it worked quite amazing but since i never saw anyone using it , I'm sort of confused if it's bad or unorthodox to use it for anything other than font-size tnx ❤️

Bond with the nearest ball.

https://codepen.io/-bloop-/pen/jOeJzqr in this given codepen, u can see there's 30 balls each with their respective x and y velocity. the intention of the code was to make so that each ball forms a bond with it's nearest ball. But apart from the first ball, all of the balls don't actually create a bond with it's nearest one unless a ball is very very close to it. Does anyone how why it happens or how I can tackle this? I've added descriptive comments in my code so it'll be easier to understand what each codeblock does. tnx ❤️

trying to solve css

so if I have

  <div>
    I work fine
    <h2>
      <span>
        I'm effected
      </span>
    </h2>
  </div>
  
  <h1>I don't work fine</h1>

  <div>
    I work fine
    <h2>
      <span>
        I'm effected
      </span>
    </h2>
  </div>
  
  <h1>I don't work fine</h1>

and I do

 :root{
      --color : red;
    }
    
    span{
      color : var(--color);
    }

 :root{
      --color : red;
    }
    
    span{
      color : var(--color);
    }

doing

    div:hover {
      --color : black;
    }

    div:hover {
      --color : black;
    }

would work but if I do

    h1:hover{
       --color : black;
    }

    h1:hover{
       --color : black;
    }

it doesn't work. why?? don't they both change the value of the variable?

does it work for unsotred array?

function findMe (target, start, end){
      
      if(start > end) 
        return "Not Found" ;
      
      const middle = Math.floor( (start + end) / 2);
      
      if( arr[middle] === target ) 
        return `found at index ${middle}`;
        
      if( arr[middle] > target )
        return findMe( target, start, middle-1 );
        
      if( arr[middle] < target )
        return findMe( target, middle+1, end);
        
    }

function findMe (target, start, end){
      
      if(start > end) 
        return "Not Found" ;
      
      const middle = Math.floor( (start + end) / 2);
      
      if( arr[middle] === target ) 
        return `found at index ${middle}`;
        
      if( arr[middle] > target )
        return findMe( target, start, middle-1 );
        
      if( arr[middle] < target )
        return findMe( target, middle+1, end);
        
    }

since it's checking if arr[middle] is less than or bigger than the target if u given unsorted array for example

const arr = [3,1,2]

const arr = [3,1,2]

and we r looking for 3 then it'll first land on 1, then check if 1 is smaller or bigger than 3. Since it's smaller than 3 it'll look on the right side but 3 in on the left side. so does that mean it'll only work with sorted array or am I getting something wrong?? i do know how to sort an array btw xD

loops and forEach

if i have for example ,

for(let i = 0; i<10; i++){
   
   for(let j = 0; j < 10; j++){
  
       if(j === 6) break;

   }
}

for(let i = 0; i<10; i++){
   
   for(let j = 0; j < 10; j++){
  
       if(j === 6) break;

   }
}

u can at any point i can stop the loop from doing any further loops using break but if I have something like,

arr1 = [1,2,3,4];
arr2 = [6,7,3,9];

arr1.forEach( itm1 => {

    arr2.forEach( itm2 => {
   
        if( itm1 === itm2 )
  
           //i would want it to stop checking for the rest of the items in arr2

      }
    }

arr1 = [1,2,3,4];
arr2 = [6,7,3,9];

arr1.forEach( itm1 => {

    arr2.forEach( itm2 => {
   
        if( itm1 === itm2 )
  
           //i would want it to stop checking for the rest of the items in arr2

      }
    }

is it possible to add something similar to break in the if condition that'll stop the forEach from doung further operation on the items from arr2??

hop issues

https://codepen.io/-bloop-/pen/MWPprJV so i basically just have a simple arc.. everytime u click it is supposed to hop. which it does, but the problem is, if u keep clicking, it seems as if with every click, it hops higher and higher, and doesn't hop the same height. why is it happening and how can I tackle this problem? also currently, when u tap it just teleports to the calculated position, i would like it to gradually go up like it does when it comes down.. how can I achieve that as well? tnx❤️❤️
