What was the most silliest mistake you have ever made just before you were unable to focus for some reason as a developer / programmer ?

Mine was to put || instead of && and wondering why some html is not rendering on my html page.

Same here...Goofing up with logical operators...👀👀👀

I can share a ton of them, but my favorite mistake is that once I created a service(in Android) and didn't declare in manifest. Funny thing is that my whole team was debugging but no one could figure it out for 30 mins. 😂😂😂

I once re-wrote the whole functionality for an endpoint we already used to take a list of IDs instead of a single ID so It's more efficient. It was done as a separate method as I also needed to retain the original call for single item.

When I was finished I pushed it, merged it and deployed it.

The FE dude tells me the next day that it doesn't work. I check the code and it turns out I never used the new functionality, I just wrote it and never replaced the old call with the new one :))))

This happened yesterday

@Hazarth I do this all the time at work, only I usually figure it out when testing it myself 😂
