Using asm.js to Generate wasm

Introduction

This is a very simple example of using asm.js to generate wasm binary file.

• math.js: The source file, writing in asm.js.
• math.wast: The s-expressions text format of WebAssembly.
• math.wasm: The WebAssembly binary file.
• index.html: The entry point of this example.

Code Details

The math.js exports two methods: add and square.

In the index.html, the loadWebAssembly method takes a url of .wasm file and convert to a WebAssembly Instance.

Preview

1. Start a web server.
2. Use the browser that supports WebAssembly to open the index.html.

Develop

1. Install Binaryen.
2. Install WABT.
3. Run ./build.sh.

        Binaryen             WABT
