Is there a JavaScript equivalent of Java's class.getName()?

In JavaScript, there isn't a direct equivalent of Java's class.getName() since JavaScript's type system is more dynamic and doesn't have the same concept of class names in the same way Java does. However, you can achieve similar functionality using different approaches. One common way is to retrieve the constructor function's name for an object.

Here's an example of how you might achieve something similar in JavaScript:

javascript

class MyClass {
    constructor() {
        // ...
    }
}

const instance = new MyClass();

// Get the constructor function's name
const className = instance.constructor.name;

console.log("Class name:", className);

In this example, the constructor property of the instance object refers to the constructor function, which has a name property that holds the name of the function (class).

Keep in mind that this approach assumes that you're working with classes and constructor functions. If you're dealing with plain objects or other types of JavaScript constructs, the method for getting a "name" might differ. Also, the constructor.name property might be an empty string for built-in objects or anonymous functions, so be cautious when relying on this property.
