Igualdade solta e estrita
== "loose" equality, compares values. It uses implicit type conversion
to Convert one of the 2 types to the other type, or converts both types.
> i.e. 5 == '5' is True because '5' would be converted to a int,
like Number('5') for example
=== "strict" equality, compares type and values. This is used more often
than loose equality.
Note:
x == null checks if x is null AND undefined at the same time. using == does NOT check if x was both
