Tested only on Ubuntu 22.04, KDE Neon User Edition (based on Ubuntu 22.04) and OSX Mojave or higher.

will probably work on other newer versions, with no changes, or with few changes in non-python dependencies (apt-get packages)

NOTE: Don't create a .sh file and run it all at once. It may will not work. Copy, paste, and execute each command below manually. :-)

var, let e const

Em JavaScript há uma comportamento chamado hoisting. O uso de var trazia algumas pegadinhas, como por exemplo, declarar a mesma variavel 2x usando var

var abc = 25
// ...
// ...
var abc = 99

"""
Sometimes in your Django model you want to raise a ``ValidationError`` in the ``save`` method, for
some reason.
This exception is not managed by Django Rest Framework because it occurs after its validation 
process. So at the end, you'll have a 500.
Correcting this is as simple as overriding the exception handler, by converting the Django
``ValidationError`` to a DRF one.
