A comprehensive guide to WebAssembly architecture, performance benefits, and future possibilities.
WebAssembly is a binary instruction format for a stack-based virtual machine that enables high-performance execution of client and server applications.
WASM combines low-level features with high-level capabilities, enabling cross-platform execution while maintaining speed and security.
Near-native execution speed
Memory-safe virtual sandbox
Seamless JS interoperability
300% adoption growth expected by 2027
98.7% across all major engines
80% faster than JS equivalents
Rust/C/C++ to WASM toolchains
// Simple WASM function
(module
(func add (param $a i32) (param $b i32) (result i32)
get_local $a
get_local $b
i32.add)
)
