## What it is
HoloJs is a JavaScript execution host for building augmented and virtual reality applications using web standards like WebGL, WebVR, WebAudio, and Canvas. It renders to Win32 windows, UWP views, Windows Mixed Reality headsets, and HoloLens, with a Spin tool for VS Code-based development.

## Use cases
- build VR apps with JavaScript and WebGL
- create holographic apps for HoloLens
- embed WebGL rendering in Win32 or UWP apps
- run WebVR experiences on Windows Mixed Reality headsets
- debug JavaScript AR/VR apps from Visual Studio Code
- add spatial audio to mixed reality apps

## When to choose
- you want to write AR/VR apps in JavaScript using web standard APIs
- targeting Windows Mixed Reality or HoloLens
- you need to embed a JS/WebGL runtime in Win32 or UWP applications

## When to avoid
- you target non-Windows platforms like Quest, iOS, or Android
- you need a modern, actively developed WebXR stack
- you prefer native C++/Unity development for mixed reality

## Facets
