JSON is not a good serialization format for chess positions or games. We have FEN and PGN for those use cases. Implementing the "business logic" for chess is quite a lot more challenging than implementing FEN or PGN (de)serialization.
Mixins are well-suited for writing chess software in JavaScript. For instance, a Knight is a "leaper", Bishops, Rooks and Queens are "riders". People have imagined many fairy pieces[^1], which mix various combinations of traits.
