It's a TweetDeck web wrapper for Windows 10. It's open source.
Why? Because I needed a TweetDeck app for my PC and there wasn't one. And everything goes open source these days.
Anyway, feel free to admire a codebase that has all the complexity of left-pad (if left-pad used Reactive Extensions) and offer me a job as a result so I can turn it down because I'm not willing to relocate to San Francisco.
Alternatively, if you want to skip all that and just install it, head over to the Microsoft Store. Or if you've already installed it and have a problem or a feature request, feel free to add it to the issues page.
Love, Mark
