Installation

Examples

import Afinn from "afinn.ts";
const afinn = Afinn({ language: "en" });
afinn.score("This is utterly excellent!");

In Danish:

const afinn = Afinn({ language: "da" });
afinn.score("Hvis ikke det er det mest afskyelige flueknepperi...");

In Finnish:

const afinn = Afinn({ language: "fi" });
afinn.score("Siellä on uusi hyvä juttu, katsokaa ja kuunnelkaa ihmeessä.");

In Swedish:

const afinn = Afinn({ language: "sv" });
afinn.score("det är inte bra");

In Turkish:

const afinn = Afinn({ language: "tr" });
afinn.score("iyi de\u011Fil");

const afinn = Afinn({ language: "tr" });
afinn.score("iyi değil");

With emoticons:

const afinn = Afinn({ language: "emoticons" });
afinn.score("I saw that yesterday :)");

NOTE: there are plans to add emoticon support to all languages, as is done in the Python implementation.
