Example
- Find meaningful names for computation units.
- Use
forcomprehensions ormapto combine computations together.
Let's say you have something like this:
if (userAuthorized.nonEmtpy) {
makeRequest().map {
case Success(respone) =>
someProcessing(..)
if (resendToUser) {
sendToUser(...)
}
...
}
}
If all your functions return Either or another Validation-like type, you can write:
for {
user <- authorizeUser
response <- requestToThirdParty(user)
_ <- someProcessing(...)
} {
sendToUser
}
