asm.js

Last updated on : 2023-03-20

Note:

asm.js shows a browser compatibility score of 75. This is a collective score out of 100 to represent browser support of a web technology. The higher this score is, the greater is the browser compatibility. The browser compatibility score is not a 100% reflection for every browser and the web technology support. However, it does give you an estimate on how much you should rely on a particular web technology in terms of browser compatibility.

Overview

The asm.js subset of JavaScript provides low-level, portable performance with high-level language semantics. Asm.js is intended to be a target for a compile step from languages like C/C++ into optimized JavaScript.
