Ruby's duck-typing is great, but it's a method that bites me in the ass. I have to go through some long-running text processing scripts or something, and after several hours, the reason for some unexpected situations ends, due to the form being a variable on NoMethodError Being out of it comes out. Zero .
Now, once this happens, this is usually a simple fix, but if I can guess these better estimates, then it would be good, or at least these types of errors Will handle better. Sorry for the ambiguity of the question, but this kind of error is too much for me and I wonder if there is a good way to avoid it.
What kind of "error" for Ruby?
Look upwards This is useful in many programming criteria, but it is particularly useful when your There is no compiler to help catch these types of errors, to deny specific types of values for a parameter.
In short, DBC allows you to leave a worldly inquiry to make an assumption about a parameter, which guarantees to catch this assumption.
