The main difference is that NaCl used a plugin API (PPAPI). WebAssembly, like asm.js, can access JavaScript, and so it has indirect access to DOM APIs, with no new powers over the existing web. The main point of wasm, from my perspective, is startup speed. wasm will allow much smaller downloads of large codebases, and much faster parsing (due to the binary format). For small programs this might not matter, but for big ones, it's a huge deal. |
