this is a very vague statement. lua is used in a lot of environments and is very performant. you can use it inside nginx (openresty) to process requests at a pretty large scale. you can use it inside of redis. lua and javascript are somewhat interchangeable aside from the fact that js has a much larger ecosystem. sure there are situations where lua might be a bad choice but based on your remarks you make it sound like it sucks anywhere except inside a game engine.
