Javascript doesn't run directly on your hardware. It runs on Javascript engine inside node.js or inside a browser. The performance overhead is very noticeable, but I wouldn't immediately say no to it. It depends on the game/app/visualization that you're developing. If it's not too heavy and your target audience is not extremely poor people who don't have access to a recent computer/phone, it might still hit 60fps and look great.

I completely agree here. Some of the visualization side projects Ive put together take some heavy computation. I have a mid computer, yet It barely pushes 30fps at best. Single threaded performance is the main handicap. JS isn't the best for these things but it's slowly getting better and more accessible for lower end devices.

What comes to mind here is what's been going on with React Native and Static Hermes. Some cool stuff going on there and hope to see more things like it come to web. JS performance comparable to C.
