Optional
This library provides java-like optionals to filter, map and process values depending on if they're present or not.
I created this lib because I like functional programming think that Optionals are a good way to clean up code.
Yes, I know that typescript has the optional operator (?) but sometimes this isn't enough, like when I want to filter values or fail instantly if a value is empty.
How to use
Install it with yarn or npm using yarn add @mrdrogdrog/optional or npm i @mrdrogdrog/optional.
API
In addition to the traditional java-like optional functions I added some more useful functions like isEmpty, orThrow and guard. Check the docs folder for the whole API.
Build
You can build this lib by running yarn build.
Run tests with yarn test.
To check the code style use yarn lint.
