WebAssembly Tools

WebAssembly (WASM) is a binary instruction format for a stack-based virtual machine, designed as a portable compilation target for programming languages.

Key Features:

• Fast: Near-native performance in web browsers
• Safe: Memory-safe, sandboxed execution environment
• Portable: Runs on all major browsers and platforms
• Compact: Efficient binary format for fast downloads

Common Use Cases:

• High-performance web applications
• Games and graphics engines
• Video/audio codecs and processing
• Cryptography and compression
• Scientific computing and simulations
• Porting desktop applications to the web

Getting WASM Hex:

# Using xxd (Linux/Mac):
xxd -p module.wasm | tr -d '\n' | fold -w2 | paste -sd ' '

# Using Node.js:
const fs = require('fs');
const wasm = fs.readFileSync('module.wasm');
console.log(Array.from(wasm).map(b => b.toString(16).padStart(2, '0')).join(' '));
