Tabs vs Spaces, Brace placement, etc
Who cares? We aren’t living in the 80’s. Most IDEs automatically detect and match indenting, it’s not like you need to
press space X times anymore. Tools can catch and fix mismatches. Flip a coin, pick one, configure your tools, and be consistent.
As Bill Sourour says:
Over the past 20+ years, I’ve followed every imaginable trend. I’ve followed the different conventions of different languages. None of it has impacted my bug count or made my code any more efficient.
There are also plenty of tools dedicated to auto-formatting code. Many of these come as plugins for IDEs that auto-format as you go or when you save. I highly recommend finding a few of these and providing pre-tuned configs for your developers. Takes all the hassle out of it.
