Too Long; Didn't Read
Web Assembly, or wasm, is a low-level language that runs inside the browser transforming it into a virtual machine. Its intentions are portability through the browser and running any application natively. C/C++ and C# the most used languages in the games industry already have compatibility with wasm. The future of browser-based games still seems a bit uncertain, but only time (whatever that may be) will tell, it is still a bet for the future and only time will tell.
