WebAssembly is a new type of code that can be run in modern web browsers it is a low-level assembly-like language with a compact binary format that runs with near-native performance and provides languages such as C/C++, C# and Rust with a compilation target so that they can run on the web. Allowing random drive-by software to execute Is lock-free synchronization always superior to synchronization using locks? disable WASM. specific type of behavior. The newer WebAssembly.compileStreaming/WebAssembly.instantiateStreaming methods are a lot more efficient they perform their actions directly on the raw stream of bytes coming from the network, cutting out the need for the ArrayBuffer step.
