Contributions summary:Jeff's commits primarily focus on improving the test suite for the chess.js library. They implemented unit tests to measure and display the performance of key functionality, like perft, checkmate, and stalemate detection, adding timing and node counts to each test. They refactored the test library to use a more modern testing framework (Jest) and expanded test coverage by adding tests for algebraic notation, get/put operations, FEN serialization, and makeMove functionality.
