// testJs.c -- single-threaded Duktape (JavaScript) adapter tests.
//
// Mirrors testSquirrel/testLua: scalar/string/array/object marshalling between JS
// and CalogValueT, a JS function pinned as a CalogFnT and invoked from C through the
// broker, a closure passed as a native argument and called back, and the export
// error paths. Single-threaded on purpose (a CalogFnT is invoked on its owner's
// heap thread); the threaded engine path is testEngineJs. Built under ASan+UBSan.
