In a quest for faster web experience, a group of engineers from Microsoft, Google, and Mozilla are planning its successor, named WebAssembly.
WebAssembly is a project to create a new bytecode (a machine-readable instruction set that’s quicker for browsers to load than high-level languages) that’s more efficient for both desktop and mobile browsers to parse than the full source code of a Web page or app.
The reason for creating a binary format was to tackle the bottleneck in JavaScript execution.
According to reports, WebAssembly is in its early days and neither its specifications nor its high level design have been finalized yet.
