I'm glad that you said, "can be" because language flexibility is a two way street. You can abuse dynamic typing for good and for evil. I, personally, don't think that's a case for declaring it not worthwhile, rather it reenforces investing the time to properly understand the language.

Fortunately, at this stage, we get the best of both worlds with syntax validators and linters. Abuse as appropriate (whatever that means) and be warned about the rest.
