How to get a JavaScript object's class?

Question

I created a JavaScript object, but how I can determine the class of that object?

I want something similar to Java\'s .getClass() method.

Answer 1

i had a situation to work generic now and used this:

class Test {
  // your class definition
}

nameByType = function(type){
  return type.prototype["constructor"]["name"];
};

console.log(nameByType(Test));

thats the only way i found to get the class name by type input if you don't have a instance of an object.

(written in ES2017)

dot notation also works fine

console.log(Test.prototype.constructor.name); // returns "Test"
