Question

Why is this example below not outputting "hello world"? Instead, I am getting:

TypeError: _base2.default.test is not a function

(it is being transpiled with Babel)

file1.js

import Example from './file2';
console.log(Example.test());

file2.js

export default class Example {
  test() {
    console.log('hello world');
  }
}

Accepted Answer

You are only importing the class, but not making an instance of the class

Try

var myInstance = new Example()
myInstance.test()

Answer 2

If you want to call a method as a class method (without creating an object instance) you can try static methods.

You can change the file2.js as,

export default class Example {
  static test() {
    console.log('hello world');
  }
}

then call it by using the class name in file1.js as

import Example from './file2';
console.log(Example.test());

Refer James Maa answer if you want to call it as an instance method.
