Introduction to WebAssembly
WebAssembly, often abbreviated as Wasm, is a binary instruction format that enables high-performance execution of applications in web browsers. This experimental project explores how Wasm can be used for complex computations, game development, and AI inference in the browser.
🔧 Key Features Demonstrated
WS
Wasm Speed
Demonstration of sub-millisecond startup time for WebAssembly modules.
3D
3D Rendering
Using Wasm to power complex 3D physics simulations in the browser.
AI
AI Inference
On-device machine learning with WebAssembly-accelerated inference.
🔍 Architectural Insights
Binary Format
- • 100% binary format with no plaintext overhead
- • 50% smaller download size vs JavaScript
- • Native module loading in 8-12ms
- • Memory allocation optimized for heap performance
Execution Engine
- • Just-in-Time compilation for fast startup
- • Ahead-of-Time compilation available
- • Memory isolation for security
- • Garbage collection integration
🧪 Example Code
// C++ Source
int fib(int n) {
if (n <= 2) return 1;
return fib(n-1) + fib(n-2);
}
// WebAssembly Output
(module
(func $fib (param $n i32) (result i32)
(if (i32.le_s (local.get $n) (i32.const 2))
(return (i32.const 1))
)
(return
(i32.add
(call $fib (i32.sub (local.get $n) (i32.const 1)))
(call $fib (i32.sub (local.get $n) (i32.const 2)))
)
)
)
