I totally can imagine how in the future there are these archeologists among all those JavaScript devs working for them trying to understand that weird language that Chrome was once written in, still in use decades after the company that built it went away. Countless attempts to improve anything in that ancient code base failed since by that point, every little quirk that browser exposed was depended on by some essential system running a power plant, hospital or internet core infrastructure. So the archeologists rather try to find even more quirks that can be abused for performance.
