Cloudflar workers uses WebAssembly, as it offers a JavaScript execution environment, that can instantiate and run WebAssembly. This is awesome, as serverless applications are usually contrained by their execution time. Meaning, tht using WebAssembly for computationally intensive tasks, rather than JavaScript, can greatly reduce execution time. This is great for both budget, as well as doing something like manipualting images on demand per a network request to a server.
