Strong type is checking the types of variables as soon as 
possible, usually at compile time. While weak typing is 
delaying checking the types of the system as late as 
possible, usually to run-time. Which is preferred depends 
on what you want. For scripts & quick stuff you’ll usually 
want weak typing, because you want to write as much less 
(is this a correct way to use Ensligh?) code as possible. 
In big programs, strong typing can reduce errors at compile 
time.
