3. Destructuring: Destructuring is a powerful feature that allows you to extract data from arrays and objects easily. It makes your code more concise and readable by reducing the number of variables you need to declare. Destructuring is especially useful when working with complex data structures, such as nested arrays and objects.
4. Spread Operator: The spread operator is a convenient way of expanding arrays and objects. It allows you to spread the elements of an array or the properties of an object into another array or object. The spread operator is useful for creating copies of arrays and objects, merging arrays, and passing arguments to functions.
6. Async/Await: Async/await is a modern way of handling asynchronous code that builds on top of promises. It allows you to write asynchronous code that looks and behaves like synchronous code. Async/await makes it easier to reason about asynchronous code and makes error handling more straightforward.
