/**
 * Implements annotated function in JavaScript and automatically imports is to Wasm.
 * [code] string must contain JS expression that evaluates to JS function with signature that matches annotated kotlin function
 *
 * For example, a function that adds two Doubles via JS:
 *
 *      @JsFun("(x, y) => x + y")
 *      fun jsAdd(x: Double, y: Double): Double =
 *          error("...")
 *
 * This is a temporary annotation because K/Wasm <-> JS interop is not designed yet.
