CSP是否要求“严格使用”

Question

Do I have to use the "use script" directive when serving my code with Content Security Policy enabled? I cannot find any reference that says it is enforced but many code examples have it. I don't know if it's just best practice or required ?

"use strict" is good practise entirely independent of the use (or otherwise) of CSP.
