isGeneratorObjectRaw

external fun isGeneratorObjectRaw(value: Any?): Boolean(source)

Returns true if the value is a generator object as returned from a built-in generator function. This only reports back what the JavaScript engine is seeing; in particular, the return value may not match the original source code if a transpilation tool was used.

function* foo() {}
const generator = foo();
util.types.isGeneratorObject(generator); // Returns true
