Not an issue but just had a question about sequilizejs and the purpose of using mixins

[gautamz07]

Whats the purpose of creating a separate file for mixins in the file HERE ?

I see it is being used HERE. But what is the reason these mixin functions are being but in a separate file ? is this some kind of a pattern or good practice ? Also what would be the alternative to this ? or rather i should ask if we did't create the mixin file would there be alot of spaghetti code in the codebase ? if somebody could shed light on this , i would highly appreciate it.

Thank you.
