Destructuring, often referred to as "destructuring assignment," is a JavaScript expression that makes it possible to extract values from arrays or properties from objects into distinct variables. It provides a concise way to access and assign values.

When destructuring an array, you can assign elements to variables in the order they appear. For example, if you have an array `[a, b, c]`, you can destructure it into separate variables `x`, `y`, and `z` like this: `const [x, y, z] = [a, b, c];`. This assigns the first element of the array to `x`, the second to `y`, and the third to `z`.

Object destructuring works similarly but uses property names. If you have an object `{ name: "Alice", age: 30 }`, you can extract `name` and `age` into variables like this: `const { name, age } = { name: "Alice", age: 30 };`. This creates variables `name` and `age` with the corresponding values from the object. You can also rename variables during object destructuring, for instance, `const { name: personName, age: personAge } = { name: "Alice", age: 30 };`.

Destructuring is particularly useful for working with function parameters, especially when dealing with objects. It simplifies code by avoiding repetitive access to object properties or array elements. It can also be used to swap variable values easily without needing a temporary variable. The syntax is designed to be readable and expressive, making JavaScript code cleaner and more maintainable.
