[Idea]: add WebAssembly implementations for stats/strided routines

[kgryte]

Idea

We've worked toward compiling BLAS routines to WebAssembly and offering ergonomic APIs for interfacing between JavaScript and WebAssembly binaries (see https://github.com/stdlib-js/stdlib/tree/develop/lib/node_modules/%40stdlib/blas/base/wasm). The goal of this project would be to extend these efforts to the stats/strided namespace, such that, for each typed interface in stats/strided/(d|s|c|z|)*, there would be a corresponding WebAssembly package in stats/strided/wasm/*.

Expected outcomes

Users wanting to potentially accelerate computation of strided statistics routines will be able to consume a corresponding WebAssembly API.

Status

Work has primarily happened in https://github.com/stdlib-js/stdlib/tree/develop/lib/node_modules/%40stdlib/blas/base/wasm. The efforts there would need to be replicated for the stats/strided/* namespace.

Involved software

Emscripten, which is necessary for compiling C to WebAssembly. stdlib already offers tooling for automatically installing the emsdk and getting things up and running.

Technology

C, JavaScript

Other technology

None.

Difficulty

3

Difficulty justification

Given that most stats/strided/* routines are straightforward one-dimensional strided array interfaces, developing the wasm packages should be similarly straightforward. The main time-consuming task will be writing tests and documentation.

Prerequisite knowledge

Some familiarity with WebAssembly will be helpful. Experience with JavaScript.

Project length

90/175/350. Can be scoped accordingly.
