The problem is the underlying API. parseInt(“550e8400-e29b-41d4-a716-446655440000”, 10) (this is a UUID) returns 550. If you’re expecting that input to not parse as a number, then JavaScript fails you. To some degree there is a need for things to provide common standards. If your team all understands how parseInt works and agrees that those strings should be numbers and continues to design for that, you’re golden.

Yeah good point. I suppose the problem is this function that operates on numbers allows numeric strings to be passed in in the first place. The only place where I would really expect numeric strings to exist is captured directly from user input which is where the parsing into a numeric data type should happen, not randomly in a library function.
