Hi everyone, something Iâve meant to ask over the years, as Iâve seen lots of variation and was taught something else in the day... What is the suggested way of naming parameters? I was taught {âaâ/âanâ}DataType, so it would be: #name: aString Which works ok (although falls apart if you refactor as the tools donât interpret it - although I guess could be improved to do so) However often I find myself wanting to communicate a bit better as in: #name: fullNameString Which isnât strictly a datatype (and I tend to leave out the a/an when I do this). But it feels a bit off piste and it does make me consider whether my selector is named badly and should be: #fullName: aString Which takes me back to the convention I learned long ago. This said however, we often need to match similar #on:do, #in: generic selector names and then itâs not always obvious the intent of parameter. Any thoughts to share? I ask because for exercism, we should try and set a good example. Tim Sent from my iPhone
