Array destructuring is a powerful feature in JavaScript that allows you to extract multiple values from an array into distinct variables in a concise and readable way. In the context of React, it can be particularly useful for handling props, state, and data passed down through components.

Understanding Array Destructuring
Array destructuring simplifies the process of extracting values from arrays and assigning them to variables. Instead of accessing array elements using indexes, destructuring allows you to unpack values directly into variables. Here’s a basic example:
// Without destructuring
const myArray = ['apple', 'banana', 'cherry'];
const firstFruit = myArray[0];
const secondFruit = myArray[1];
const thirdFruit = myArray[2];
// With destructuring
const [first, second, third] = myArray;
console.log(first); // 'apple'
console.log(second); // 'banana'
console.log(third); // 'cherry'
