I'm making a Google Apps Script function that takes two parameters: a Spreadsheet object and a Transaction object, which I created. How can I specify that I want my parameters to have that type?
I'm looking for this functionality:
function addTransaction(Spreadsheet sheet,Transaction t){//blah blah blah doesn't matter}
Google Apps Script is based on JavaScript which is not a statically typed language. You can't enforce types. You will need to manually check the types in your function body.
