Web Assembly Demystified: A Comprehensive Overview
3 min read
WebAssembly (Wasm) is a low-level, binary instruction format for a stack-based virtual machine that is designed to run in modern web browsers. It is an open standard and is supported by all modern web browsers, including Google Chrome, Mozilla Firefox, and Microsoft Edge.
WebAssembly is designed to be fast and efficient, and it is able to run in the browser at near-native speeds. This is because WebAssembly is compiled ahead of time (AOT) and is optimized for the specific hardware and operating system it is running on. This makes it a good choice for applications that require high performance, such as games or video processing.
WebAssembly is also designed to be secure, as it runs in a sandboxed environment and is isolated from the rest of the web page. This makes it a good choice for applications that require a high level of security, such as online banking or cryptocurrency exchanges.
To use WebAssembly in a web application, developers first need to compile their code into the WebAssembly binary format. This can be done using a tool such as Emscripten, which is an open-source compiler that converts C++ code into WebAssembly.
