The worst bug was also the weirdest, incidentally.
So we had an array of objects that needed to be sorted by one of their attributes which is a numerical value. We had a bug report which stated that sorting (using JS array.sort) is not working on production (on Google Chrome) and, sure enough, it didn't work.
When we opened the page with the issue present on a local machine, everything worked as expected. There was no difference in the code and everything was up to date. It was a literal case of "it works on my dev machine".
Turns out, Node JS's sorting algorithm is not very consistent across environments. More info here: v8.dev/blog/array-sort
We have moved the sorting algorithm to lodash's sort method and everything worked correctly.
For further actions, you may consider blocking this person and/or reporting abuse
We're a place where coders share, stay up-to-date and grow their careers.
Hello, thanks for the question! :)
