Bug#942455: ITP: webassemblyjs -- Toolchain for WebAssembly

[Pirate Praveen]

Package: wnpp
Severity: wishlist

Upstream repo <https://github.com/xtuc/webassemblyjs> has many related 
node modules.

These will be packaged as a single binary package (node-webassemblyjs) 
and maintained at <https://salsa.debian.org/js-team/webassemblyjs>

This is a dependency on webpack 4.7+ and we need webpack 4.30 for acorn 
6 transition.
