function Animal(name) { this.name = name; }

Inheritance in JavaScript can be implemented using constructors, prototypes, and the Object.create() method. For example:

Error handling in JavaScript can be achieved using try-catch blocks, where you can catch and handle specific errors. Additionally, you can use the throw statement to throw custom errors.

const promise = new Promise((resolve, reject) => { // Asynchronous operation setTimeout(() => { resolve("Data loaded successfully."); }, 2000); });

In JavaScript, null represents the intentional absence of any object value, whereas undefined indicates a variable that has been declared but not assigned a value.
