New Feature

function
- add LazyArg
add tap (dual) (aka chainFirst / chainFirstW) to:
- Either
- IO
- IOEither
- IOOption
- Option
- Reader
- ReaderEither
- ReaderIO
- ReaderTask
- ReaderTaskEither
- State
- StateReaderTaskEither
- Task
- TaskEither
- TaskOption
add tapError (dual) (aka orElseFirst / orElseFirstW) to:
- IOEither
- ReaderEither
- ReaderTaskEither
- TaskEither
add flatMapNullable (dual) to:
- Either
- IOEither
- ReaderEither
- ReaderTaskEither
- StateReaderTaskEither
- TaskEither
add flatMapOption (dual) to:
- Either
- IOEither
- ReaderEither
- ReaderTaskEither
- StateReaderTaskEither
- TaskEither
add liftNullable to:
- Either
- IOEither
- ReaderEither
- ReaderTaskEither
- StateReaderTaskEither
- TaskEither
add liftOption to:
- Either
- IOEither
- ReaderEither
- ReaderTaskEither
- StateReaderTaskEither
- TaskEither
add flatMapEither (dual) to:
- IOEither
- ReaderEither
- ReaderTaskEither
- TaskEither
Array
- add index to flatMap
NonEmptyArray
- add index to flatMap

2.14.0

1 year ago

New Feature

add flatMap to
- Either
- IOEither
- Reader
- ReaderEither
- ReaderIO
- ReaderTask
- ReaderTaskEither
- StateReaderTaskEither
- TaskEither
- NonEmptyArray
- ReadonlyNonEmptyArray
- Tree
- Array
- Identity
- IO
- IOOption
- Option
- ReadonlyArray
- State
- Task
- TaskOption

the gist is:

you can replace chain / chainW with flatMap
you can call flatMap in 2 ways: pipe(ma, flatMap(f)) (data-last, aka pipeable) or flatMap(ma, f) (data-first)
