[typescript] Get an object's class name at runtime

You need to first cast the instance to any because Function's type definition does not have a name property.

class MyClass {
  getName() {
    return (<any>this).constructor.name;
    // OR return (this as any).constructor.name;
  }
}

// From outside the class:
var className = (<any>new MyClass()).constructor.name;
// OR var className = (new MyClass() as any).constructor.name;
console.log(className); // Should output "MyClass"

// From inside the class:
var instance = new MyClass();
console.log(instance.getName()); // Should output "MyClass"

Update:

With TypeScript 2.4 (and potentially earlier) the code can be even cleaner:

class MyClass {
  getName() {
    return this.constructor.name;
  }
}

// From outside the class:
var className = (new MyClass).constructor.name;
console.log(className); // Should output "MyClass"

// From inside the class:
var instance = new MyClass();
console.log(instance.getName()); // Should output "MyClass"
