The Hidden Patterns of WebAssembly
Published • September 2025
WebAssembly's binary format isn't just about speed - it's a carefully designed language of bytes. Each instruction is crafted to optimize execution while maintaining compatibility with web standards.
(module
(func $add (param $x i32) (param $y i32) (result i32)
get_local $x
get_local $y
i32.add)
(export "add" (func $add))
)
