QUESTION
I created table of 500 rows, and reversing it on click feels slow, subjectively like 500ms or so.
Is it reasonable performance? I have a feeling that reversing table of 500 lines in JS should be faster.
Svelte demo and Pure JS demo.
Pure JS feels much faster than Svelte
Table.svelte

Answered 2021-Jun-11 at 23:14I first thought that it has something to do with the index not working properly, but when adding a 'slice' button and a fade-effect it seems to work fine -> the first item fades out and after it was totally removed the other elements move up.
SEE THIS slightly modified version of yours
- 'slice' button and effect on StringView added
- timer in console tracking time before -> after Update
Nevertheless, since I already wondered how to properly define the id on arrays an nested each loops (Nested each loops over array in Svelte - how to set unique id / key?) I made a version with objects instead of row-arrays and just one Component for the rows. When comparing the time for updating, it's almost twice as fast ( firstLoad/Update --> ≈700ms/250ms --> 330ms/160ms (in Firefox)) -> See this REPL
I'm still wondering if this might be optimized, since even when the id/key seems to work, every TableRow-Component logs an Update when the order is reversed or the first element is sliced. I once made a very simple example which behaves differently and only elments without id log an update -> see this REPL
(this part of your code could be written shorter ->

I want to provide both the data and variable names in a function. This is because users might provide datasets with different names of the same variables. Following is a reproducible example that throws an error. Please refer me to the relevant resources to fix this problem.
Also, please let me know what are best practices for writing such functions? In the documentation, should I ask a user to rename their columns or provide a dataset with only the required columns?

I am trying to convert a simple webpage I have into a PWA in case the site it uses goes down.

From Chrome 89 March 2021, it gives a warning if this check does not pass: The installed service worker fetch event returns an HTTP 200 status code (indicating a successful fetch) in simulated offline mode.
So, in your case, the service worker should return a cached 'index.html' when fetch(event.request) is failed.

I have a working R function that uses a for-loop. To take advantage of julia's speed, I am re-writing the R function julia.
R function ...ANSWER
Answered 2021-Mar-22 at 23:09- I do not see a problem with the line that you indicated. The
TypeError: non-boolean (Missing) used in boolean context
occurs because of line 115 of your function:bn_complete[t] = ifelse(B_Emg[t] < BMIN | B_Emg[t] > 0, BMIN, B_Emg[t])
There is some operator precedence issues and issues with using missing. I believe this may be closer to what you intend.
