Warning in web javascript editor

Question

I have this code I have written: https://code.sololearn.com/Wzzt1aZK3nQC/#js and while when it was shorter did trigger some warning that I fixed now that the code has become longer all I get is a warning on line 179 that says "Too many errors. (67% scanned)."

Has anybody seen this before? Does anybody know how to fix it?

EDIT: The same problem have the following codes:
https://code.sololearn.com/WM6UzehGJPHE/#js on line 158,
https://code.sololearn.com/WNSd1PCfSo5s/#js on line 156,
https://code.sololearn.com/WGObAy7i6amA/#js on line 247

My guess is there are a lot more.

Answer 1

Look at my answer in this thread, there are my assumptions about how the SL Playground works and links to resources where you can check your code.

Answer 2

@Basile Laderchi, I also don't know the exact answer yet...
Thank you for one more useful link👍

Answer 3

@NezhnyjVampir: useful links, but still no answer to why SL Playground doesn't check after some length.

BTW I found this one https://eslint.org/demo/ that works way better

Answer 4

@Mark: line 9 is "var pairs0 = Array.from(....);".
There is no mistake on that line.
If I delete some lines (eg. empty the buildgalaxy, gen_rnd_number and the makesystem functions) then the code obviously doesn't run, but it doesn't give me any warnings.

Answer 5

line 9 bar pairs0 =
pairs0 is equal to nothing
