To be fair, Sequelize makes itself look like a joke. I normally wouldn't call out an individual library to shit on, because I understand that a lot of work has gone into it.

But I used it for years and it was always buggy. Sometimes options wouldn't work correctly because the authors liked to do that clever JavaScript thing where they write `foo = optional_thing || default_value` even for BOOLEAN options. I always had issues with it not being able to truncate/drop tables correctly that had foreign keys (it didn't attempt to order them intelligently), some of the options weren't compatible with each other even though they were orthogonal (I'm thinking about the snake_casing options and the created_at/updated_at column features), etc, etc.

It just... didn't actually work. Over many versions. I think I used it from late 3.x somewhere through 5.x.

Maybe it's awesome now, but I doubt it.
