So if === is the best choice to practice, is !== also a better choice than != to avoid future problems in the script?

Answer 1

!== When you want to check value and type.

Answer 2

nothing is good or bad.
use as per your convenience and requirement.

Answer 3

No it's not like that.It differs where and how you want to use it.When you know that variables are of same type use!= and if you don't know the types use !==

Answer 4

think of the first character (either = or !) as saying is or is not
== "is" equal to
!= "is not" equal to
=== "is" exactly equal to
!== "is not" exactly equal to

I'm not sure if that's the rationale but it helps me
