Coq vs Lean

Developers should learn Coq when working on safety-critical or high-assurance software where correctness is paramount, such as in aerospace, finance, or security applications meets developers should learn lean to optimize software development processes, reduce inefficiencies like overproduction or waiting times, and deliver higher-quality products faster, especially in agile or devops environments. Here's our take.

Coq

Nice Pick
