A WebAssembly study - 【126Kr】 I looked into WebAssembly this weekend.

WebAssembly text format: LESv3 · Loyc. 21 Aug 2016 Background: WebAssembly is a new technology being standardized for running native applications (e.g.
C/C++/Rust) on the web. It used to be an expression-based language that was typically viewed as an abstract syntax tree (AST) — basically a high-level assembly language, moreso than C ever was. Recently, however, the design shifted into a postorder “stack machine” which supports all the code that could have been expressed as an AST, plus some “oddball” code that is not expressible as an AST (details). The text format of WebAssembly is not yet standardized; this article is the second followup to my proposal to use LES, an open-ended multi-purpose code format. Right now I’m gathering opinions. Now that Wasm is moving toward a stack machine, I think that LES is now more relevant than ever, because there seems to be a need for not one Wasm language but two: one for Wasm itself, and another for the pseudo-wasm AST used by producers (i.e. binaryen). What is LES? (memory 1) ... An early look at WebAssembly.
Keeping on the cutting edge of frontend technology can feel like you're trying to herd cats at times.
The huge choice of tooling, libraries and frameworks has simultaneously improved the developer experience and caused a lot of buzz about 'fatigue' and 'churn' with people trying to keep up. In this post I'm going to take a look at what may significantly change how we develop webpages in the future and become The Next Big Thing™: WebAssembly. WebAssembly is about as bleeding-edge as you can get at the moment. Even the logo hasn't been finalised yet. But before we look at WebAssembly, we need to talk about translating compilers. A translating compiler (transpiler) is a compiler that can take the source code of a program written in one programming language and produce the equivalent source code for another programming language.
The conversion chain is D-to-LLVM-to-C-to-ASMJS, and uses ldc, Emscripten, and an unexpectedly useful tool from the Julia community. Demo here: First attempt with LDC. Wat is WebAssembly? Build Your First Thing With WebAssembly - Culture of Development. When I first heard of WebAssembly it sure sounded cool and I was super excited to start trying it out.
You can easily find lots of articles on that topic over the web, so I'm not planning to explain in details the theory... Rather than summing up again the same information from different sources, this blogpost is a deep dive from my own experience into digging how to compile a non-trivial piece of C++ into asm.js and Web Assembly (wasm). Then running them inside the browser from a custom test in order to benchmark the performances. Results are satisfying, to say the least. If you are ready for a sneak peek at the future of web development, keep reading! I - Setting up the Emscripten tool chain 2/ You will then build the SDK from source as per those instructions. . Meta Magic: WebAssembly Hello World! Having done so much browser development in the past I have been watching WebAssembly closely.
This past weekend I finally got some time to read through the current documents and mess around with various projects including WAVM. In the process after discovering no one seems to have bothered to create a Hello World! Program, so I did. WebAssembly currently has two formats, a binary format and an editable AST form. (They are not final and there is even talk of going with something other than the AST form for the official text mode.)

WebAssembly is an emerging standard whose goal is to define a safe, portable, size- and load-time efficient binary compiler target which offers near-native performance—a virtual CPU for the Web.
