I originally wrote a long introduction to this article about Scala Options, but I decided to keep that introduction for a future second article in this series. For this article I’ll just say:
- idiomatic Scala code involves never using null values
- because you never use nulls, it’s important for you to become an expert at using
Option,Some, andNone - initially you may want to use match expressions to handle
Optionvalues - as you become more proficient with Scala and Options, you’ll find that match expressions tend to be verbose
- becoming proficient with higher-order functions (HOFs) like
map,filter,fold, and many others are the cure for that verbosity
