Issues and Steps to Reproduce

Replaces this with steps to repro your issue.

setBaselineFunction doesn't seem to be available in JavaScript build.

In the Java and C# builds you can set a baseline function like this (copied from YogaNodeTest.java:

child2.setBaselineFunction(new YogaBaselineFunction() {
      public float baseline(YogaNode node, float width, float height) {
            return 0;
      }
});

Expected Behavior

Describe what you expected would happen.

Ability to set function in JS, e.g. by using child2.setBaselineFunction((node, width, height) => 80);

Actual Behavior

Describe what actually happened.

Error is thrown TypeError: child2.setBaselineFunction is not a function

Start by comparing the Java and C# baseline-function APIs, including YogaNodeTest.java, with the JavaScript build entry point for setBaselineFunction. Expose equivalent JavaScript behavior for the callback described in the issue and verify that child2.setBaselineFunction no longer throws a TypeError.
