Uncaught SyntaxError: Identifier 'tittle' has already been declared

@wordlesspirate
not entirely sure without a snippet of code to look at, @rajirashed2010 , but if I had to guess, there must be a variable in our code that you are reusing. something along these lines:
let name = "a"

let name = "b"
let name = "b"
    ^

SyntaxError: Identifier 'name' has already been declared
rajirashed2010
@rajirashed2010
thanks @wordlesspirate not that ma.
@wordlesspirate pls how can i sent my code to you so u can play around it together please
Vanessa Correia
@wordlesspirate
if it is not too long of a piece of code, i would say you can paste here. just make sure to use quotations code inside so your code formats into a snippet, makes it a little easier to read.
quotations i mean these: ```. at the start and end of your code block.

Hey guys I use cheerio to scrape this table but it return nothing. Did I somehow did wrong ?

<table class="table trackTable">
                    <thead>
                            <tr>
                                <th colspan="4">Consignment No: MY37011088606</th>
                            </tr>
                        <tr>
                            <th>Consignment No</th>
                            <th>Date &amp; Time</th>
                            <th>Status</th>
                            <th>Location</th>
                        </tr>
                    </thead>
                    <tbody>
                                <tr>
                                    <td>MY37011088606</td>
                                    <td>03/07/2020 14:58:43</td>

                                        <td><b>Delivered</b></td>

                                    <td>Butterworth</td>
                                </tr>
                          .....
                </table>

and my code was

$ = cheerio.load(response['data']);

            $.html();

            $('.table#trackTable').each((index, element) => {
                if (index === 0) return (true);

                console.log(element)
            });

Any idea ? is the naming of the selctor wrong?

in the browser i did

$(".table > tbody:nth-child(2)").each(function(i,item) { console.log(item.innerText) });

and it return something , but cheerio doesn't

hi guys. I need help. I have this Api that I am trying to consume: https://torre.bio/api/bios/ and I usually get this error Access to XMLHttpRequest at 'https://torre.bio/api/bios/john' from origin 'http://localhost:3000' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. on close investigation at the network tab I found out that any time I hit the above url I am being redirected to https://bio.torre.co/api/bios. Which seems to show that I may need a proxy server backend to handle access to this url. I have searched and nothing comes close to a solution. A stackoverflow respose "https://stackoverflow.com/questions/70114502/access-to-xmlhttprequest-at-from-origin-http-localhost4200-has-been-bloc " is a close answer but it was implemented with .Net. My app codebase is in react and I need help on setting up a proxy server to consume the API above. Thanks.

Hey everyone! I would like to get deep knowledge of nodejs and backend concepts. I have been working as a software dev for a 5 years already, but mostly focusing on frontend. Can you give me some hints on what I need to know to become a really good backend/nodejs developer?
Dan Stockham
@DanStockham
@kamatheuska the best thing I can suggest is getting an understanding how the http web server frameworks for nodejs work and getting comfortable building things with them
@kamatheuska NodeSchool is a good place to start but FCC has a pretty good course that immerses you enough that you can start building things efficiently
@tundeiness It is very possible that the api you're trying to reach doesn't allow for http or unsecured connections (hence, your localhost instance is unsecure)
Dan Stockham
@DanStockham
@tundeiness Either I would find way to put your local instances on port 443 which means self-signing a certificate or setup a secure backend server that acts as a façade to your api you're trying to consume.

Hi all, has anyone handled an exception with a template language? I'm using Freemarker, and my goal is to handle a null exception if there is no image to be rendered. However, I don't know what I'd return if it is null -- should I create a statement, "No image provided?"
Nevermind, I didn't realize I should do nothing in response.

@Ozenzamy-Spark

Hi all , please i have a question about the Iterative implementation of Binary Search

This is the function i create in c:

int BinarySearch(int arr[], int l, int r, int x) { while(l <= r) { int mid = l + (r - l) / 2; printf("%d\n", mid); if(arr[mid] == x) return mid; if(arr[mid] > x) r = mid - 1; else l = mid + 1; } return -1; }

This is my main function :

int main() { int arr[] = {1,2,3,5,16,15,20}; int n = sizeof(arr) / sizeof(arr[0]); int x = 16; int result = BinarySearch(arr, 0, n-1, x); (result == -1) // WE CALL THIS ternary operator. ? printf("Element is not present in array") : printf("Element is present at index %d", result); return 0; }

The question is: when i search 16 the function return -1.
If you see the number 16 is on the list any help please ??
