TypeError: x is not a constructor

Bu hatanın nedenleri

You tried to use 'new' with an arrow function, a regular value, or a non-constructable object. Arrow functions cannot be used as constructors. Some built-in objects like Symbol and Math are also not constructable.

Nasıl düzeltilir

Use a regular function or class declaration instead of an arrow function when you need a constructor. Verify the value is actually a class or constructor function. Check that the import is correct and not returning a default export wrapper.

const fn = () => {}; new fn(); // TypeError: fn is not a constructor
