Also sometimes known as “not invented here syndrome”.

Sometimes it’s useful to know how something works and to be easily able to change every piece of the stack, other times it’s a massive waste of time and the end result is a worse documented and worse developed solution than what hundreds if not thousands of people have built and tested over the years.

Depends on what you’re working on, really, I’ve seen some really unfortunate stuff once people start rolling their own security stuff and it’s not like you can ask StackOverflow about why some random bespoke library or framework is full of weird behaviour.

But for personal learning projects? Go wild!
