couldnt render a json array from servlet in ember js

am trying to render a json array which is sent from a java servlet in ember. the work flow goes like follows

1.sending an ajax request to the servlet which will return the jsonobject

2.i will get the json object and try to render in the handlebar file

the problem is when i consoled the response it came with an indexes

0: {CAPACITY: '4', PRICE: '918', RTYPE: 'basic', ID: '4'}
1: {CAPACITY: '2', PRICE: '885', RTYPE: 'villa', ID: '8'}
2: {CAPACITY: '2', PRICE: '1579', RTYPE: 'villa', ID: '5'}
3: {CAPACITY: '1', PRICE: '1526', RTYPE: 'villa', ID: '1'}

but what the server sent was

{"CAPACITY":"4","PRICE":"918","RTYPE":"basic","ID":"4"}
{"CAPACITY":"2","PRICE":"885","RTYPE":"villa","ID":"8"}
{"CAPACITY":"2","PRICE":"1579","RTYPE":"villa","ID":"5"}
{"CAPACITY":"1","PRICE":"1526","RTYPE":"villa","ID":"1"}

the controller code

export default class RoomselectController extends Controller {
    @service router;
    @tracked obj = null  ;
    @tracked price =0;
    get res(){
        var dis = this;
        const mobile = "123123123";
        $.ajax({
            url:'My',
            method : 'GET',
            dataType:'json',
            data : {mobile:mobile},
            success:function(response){
                console.log(response);
                dis.price = response[0].PRICE;//when rendered this works
                dis.obj = response;//when changed to dis.obj = response[0] it renders the first
                
                return response[0];
            },
            error: function(xhr,status,error){
                var errorMessage = xhr.status + ": " + xhr.statusText;
                alert("error " + errorMessage);
            }
        })
    }

the .hbs code

<table border ="1">
    <tr><td><b>Capacity</b></td><td><b>Price</b></td><td><b>Room Type</b></td><td><b>Room No</b></td></tr>

    
        
    <td></td>
    

    </table>

it is not working but when i use dis.obj = response[0] it works and renders only the first index how to make it render every data?

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 ...
