In the ever-evolving world of JavaScript, developers are constantly seeking ways to write more concise, readable, and efficient code. One technique that has gained significant traction in recent years is destructuring, a powerful feature that allows you to extract values from arrays or objects into distinct variables.

When combined with loops, destructuring can supercharge your coding prowess and lead to cleaner, more maintainable code.

The Traditional Approach

Before diving into destructuring, let’s revisit the traditional approach to working with arrays and objects in loops. Consider the following example:

const people = [
  { name: 'Alice', age: 25 },
  { name: 'Bob', age: 30 },
  { name: 'Charlie', age: 35 }
];

for (let i = 0; i < people.length; i++) {
  const person = people[i];
  console.log(`${person.name} is ${person.age} years old.`);
}

In this code snippet, we iterate over an array of objects representing people. For each iteration, we access the object’s properties (name and age) using dot notation. While this approach works, it can…
