Getting Started

WebAssembly (WASM) is a binary instruction format that enables high-performance applications in the browser. This guide will show you how to set up your first WebAssembly project.

// Sample Rust WASM code
use wasm_bindgen::prelude::*;

#[wasm_bindgen]
pub fn greet(name: &str) -> String {
    format!("Hello, {}!", name)
}
                        

Key Features

High Performance

Achieve near-native execution speed with WebAssembly's binary compact format.

Language Agnostic

Write programs in C/C++/Rust/WASM and run them in all modern browsers.

Examples

Image Processing

Implement complex image filters with WebAssembly's raw speed.

Cryptographic Functions

Deploy cryptographic algorithms with millisecond precision.
