asm.js is a subset of JavaScript designed to allow computer software written in languages such as C to be run as web applications while maintaining performance characteristics considerably better than standard JavaScript, which is the typical language used for such applications.

2014年8月18日 · This specification defines asm.js, a strict subset of JavaScript that can be used as a low-level, efficient target language for compilers. This sublanguage effectively describes a sandboxed virtual machine for memory-unsafe languages like C or C++.

2015年7月19日 · asm.js is regular javascript code, and is compiled into bytecode by the JS interpreter as always. However, an interpreter with asm support is supposed to do ahead-of-time compilation, and possibly to generate more efficient code representation because of …

The principal benefit of asm.js over whole new technologies like NaCl and PNaCl is that it works today: existing JavaScript engines already optimize this style of code quite well. This means that developers can ship asm.js today and it'll simply get faster over time.

asm.js. an extraordinarily optimizable, low-level subset of JavaScript. specification (work in progress) frequently asked questions. big web app? compile it! ...

In theory, it is possible to convert / compile / transpile any JavaScript operation to asm.js if it can be expressed with the limited subset of the language present in asm.js. In practice, however, there is no tool capable of converting ordinary JavaScript to asm.js at the moment (June, 2017).

Asm.js, short for Assembly JavaScript, is a subset of JavaScript. An asm.js program will behave identically whether it is run in an existing JavaScript engine or an ahead-of-time (AOT) compiling engine that recognizes and optimizes asm.js—except for speed, of course!

2023年6月29日 · asm.js. The first step to writing assembly code with no architecture dependencies was asm.js, a strict subset of JavaScript that could be used as a low-level, efficient target language for compilers. This sub-language effectively described a sandboxed virtual machine for memory-unsafe languages like C or C++.

The asm.js archive. asm.js has 3 repositories available. Follow their code on GitHub.

仕様書と実装の違いの多くは、asm.jsを拡張するもの、つまり「従来の仕様では認められないものをasm.jsとして許可する」という方向性ですが、一部には仕様バグ、つまり「asm.jsとして実行した場合と通常のJavaScriptとして実行した場合で挙動が異なる」への ...
