src/promise/pProps.ts
/**
* Promise.all for Object instead of Array.
*
* Inspired by Bluebird Promise.props() and https://github.com/sindresorhus/p-props
*
* Improvements:
*
* - Exported as { pProps }, so IDE auto-completion works
* - Simpler: no support for Map, Mapper, Options
* - Included Typescript typings (no need for @types/p-props)
*
* Concurrency implementation via pMap was removed in favor of preserving async
* stack traces (more important!).
