QUESTION
I'd ask a better question, but I don't don't know how. Thanks for your help.
***ISSUE: I'm sending array vari to a function and it's coming back changed even though I didn't return it or even use same variable name. Desired function: variable vari does not change
I've logged the function and isolated the change to the [].forEach() statement below, noted with ***. I send vari but return varis and assign to new variable sum. How does this change the vari variable?
...ANSWER
Answered 2021-May-29 at 03:19vari is a 2D array. That means that every element in vari is an array as well, and as such passed by reference and subject to mutation.
The Array.splice() method mutates its argument array. In the code, each varis[varis.length-1].splice() call modifies an array object that is copied from vari1 by reference, and therefore also vari0 whose elements are array objects that are copied to vari1 by reference. This is what causes vari to mutate.
To avoid the issue, use one these patterns:

QUESTION
I'm having trouble hiding relevant data with JS.
In my code I have data-type = "power" and data-type = "grill" which are added to the products.
I want the script to check sort filters and hide those that are not present on the page.
Unfortunately, when I have two cases, it doesn't work as it should.
Grill filters do not appear even though they should.
...ANSWER
Answered 2020-Nov-07 at 08:49You have to change your filter function. You are returning two values but it stops on first return.
Change
return !powers.includes(this.dataset.id) and return !grills.includes(this.dataset.id)
to
return !powers.includes(this.dataset.id) && !grills.includes(this.dataset.id);
I hope this will solve you problem.

QUESTION
im trying to find the cause of the following crash reported on android:
crash at (operator new(unsigned int)+22)
does it mean that memory was not allocated successfully ? and if so, adding std::nothrow and null check and exit the program is the right solution?
is there a way i can limit the program to not allocate in order to reproduce it ?
the code where it crash :
...ANSWER
Answered 2019-Mar-07 at 07:57A crash in operator new or new[] can be caused by:
- unsuccessful allocation. For example if
infolenis too large compared to the available memory. - a crash in the constructor of the object(s) being allocated. But with
GLchar, this is not very probable.
You should add code to handle the exception, by enclosing new in a try..catch block (as demonstrated here) so to terminate graciously.
If you invoke new with nothrow you should then check the returned pointer for being different than nullptr in order to avoid nasty UB.

Answered 2019-Feb-10 at 14:38I am not a Nginx expert, but it seems to me that all location directives should be inside the server directive, and currently they aren't. Also you have nested location directives that I think they aren't necessary...
Start by trying to fix that with this:
