Looking at npm projects that are good candidates for being re-written in rust / webassembly!

Primitives for representing promise states
// PromiseState provides primitives for representing a promise's "state" as a
// value.
// That's kinda abstract so let's think through it. At any given point in time
// a promise is either pending, resolved, or rejected. There's no real
// synchronous way to access this promise "state", promises only give us `then`
// and callbacks.
// In react we usually care about rendering _all_ of these possible states. For
// example, we want to show a spinner when it's loading, the results when it

Functions for querying directly into map[string]interface{}
// Package sqlmap provides functions for querying directly into
// map[string]interface{}.
// In developing really simple api endpoints, I found the boilerplate needed
// to take the results of a database query and output them as JSON to be
// really fucking annoying; make a custom struct, scan into that struct, if
// there are multiple rows do the whole rows.Next() song and dance, and if
// anything changes update the three spots each column of the result is now
// dependent on. Even when using libraries like sqlx, there's still a lot of
// extraneous code that needs to be written.

Script for signing GitHub powershell scripts with code signing certificate on Windows
#!/usr/bin/env python
# This script signs github for desktop powershell scripts.
# Powershell scripts are locked down here (via sysadmin decree), but the GitHub
# Desktop app uses powershell scripts when you right click > "Open in Git
# Shell". This is pretty much a requirement since the application can only
# handle fairly simple git operations.
# In order for these scripts to work they need to be signed. I don't remember
