How to check if a variable is an ES6 class declaration?

Question

I am exporting the following ES6 class from one module:

export class Thingy {
  hello() {
    console.log(\"A\");
  }

  world() {
    console.log(\"B\");

Maybe this can help

let is_class = (obj) => {
    try {
        new obj();
        return true;
    } catch(e) {
        return false;
    };
};
