  "account": "A functional programming language and proof assistant, Lean 4, recently outperformed a popular Rust compression library in a test. However, it fell short when compared to C-written libdeflate, considered the benchmark for DEFLATE performance. Roc, another functional language with a focus on runtime performance, showed promise in matching libdeflate's speed for non-streaming DEFLATE compression. Despite its young age and limited optimization work, Roc's performance improvements, especially on the M1 MacBook Pro, suggest it may be able to challenge libdeflate in the future.",
