Note:

When this guide is more complete, the plan is to move it into Prepack documentation.
For now I put it out as a gist to gather initial feedback.

A Gentle Introduction to Prepack (Part 1)

If you're building JavaScript apps, you might already be familiar with some tools that compile JavaScript code to equivalent JavaScript code:

• Babel lets you use newer JavaScript language features, and outputs equivalent code that targets older JavaScript engines.

var cameraZ = camera.position.z;
var planeZ = 5;
var distance = cameraZ - planeZ;
var aspect = viewWidth / viewHeight;
var vFov = camera.fov * Math.PI / 180;
var planeHeightAtDistance = 2 * Math.tan(vFov / 2) * distance;
var planeWidthAtDistance = planeHeightAtDistance * aspect;

java.lang.ClassNotFoundException: javafx.util.Pair happens because javafx.util.Pair and other classes from javafx.util are not included in OpenJDK. Options for resolving:

Switch class

Map.Entry<K, V> from java.util is similar to javafx.util.Pair.

Install java-openjfx

Install java-openjfx through your package manager. (or whatever means you used to install Java on your machine) Note that java-openjfx is compatible with OpenJDK8, not previous versions.

After installing java-openjfx, you may have to add it manually to your IDE SDK classpath. Eg in IntelliJ, you may have to go to Project Structure | SDKs | <select your SDK> | Classpath | + (the Classpath +, not the SDKs +) | and add /usr/lib/jvm/java-8-openjdk/jre/lib/ext/jfxrt.jar (which should be there now that java-openjfx has been installed) | OK
