What are these modes?

–!strict : throws errors if the number of parameters passed to a function is inappropriate, i.e., if it’s not the amount the function is expected to receive. It also classifies a variable as a type, i.e number or string based on what it is assigned to. –!non-strict : if the number of parameters a function is expected to receive is more or less, it is ok and the system wouldn’t throw error. And if variables aren’t declared a type initially, it will revert to being any. –!no-check : doesn’t even…

It’s to make your code type-safe. strict scripts will emit type errors, which aren’t actually errors, but warnings that tell you when you are possibly misusing some object.
