I can't see any numbers comparing the rust implementation and the optimised javascript. Did I miss them in the article?

  A comment upthread did the math: > The author is able to achieve a speed-up of ~4x which is close to the 5.89x achieved by the Rust implementation.

    The math is not that obvious because Rust implementation does not match 1-1 what baseline JS version was doing (e.g. it sorts only generatedMappings and not originalMappings). I will do measurements later to compare and update the post.

      Sounds good! I enjoyed the article :)

    With the caveat that it's apples-to-oranges (algorithmic changes to the JavaScript version (~4x) are not in the Rust version (~5.9x)).
