Get an object"s class name at runtime

🔥📝💻 Getting an Object's Class Name at Runtime: TypeScript Magic!

Hey there tech enthusiasts! Have you ever wondered if it's possible to unveil the class name of an object at runtime using TypeScript? 🤔 Well, you're in luck because we're about to dive into this intriguing question and equip you with an easy solution! 🚀

Imagine you have a simple class, MyClass, and you want to know its name during runtime. Perhaps you're building a debugging tool, or you're simply curious to explore the unknown depths of TypeScript! Let's take a closer look at the code snippet that sparked this question:

class MyClass {}

const instance = new MyClass();
console.log(instance.????); // Should output "MyClass"

To retrieve the name of the MyClass at runtime, we can use the constructor property. This property is available on every object instance and refers to the class constructor that created the object. By accessing the name property of the constructor, we can obtain the desired class name! 🎉

So, to get the class name, replace ???? with instance.constructor.name:

console.log(instance.constructor.name); // Outputs "MyClass"

Isn't that simple? Now you can effortlessly extract the class name for any object at runtime in TypeScript! 🌟

🔎 Common Issues and Caveats

While this solution works like wizardry, there are a few things to keep in mind:

1. Anonymous Classes: If you're dealing with anonymous classes, the constructor.name property will return an empty string. It's essential to name your classes explicitly to utilize this technique effectively.

2. Inheritance and Subclasses: If you have subclasses that extend the base class, accessing instance.constructor.name will return the subclass name, not the base class name. Keep this in mind if you're working with inheritance and need to identify the actual base class.
