📥 Problem Statement:
Write a JavaScript function to return an array of objects containing both key and value pairs from an object.

📊 Example:

Input:
{ a: 1, b: 2, c: 3 }
Output: [ { key: 'a', value: 1 }, { key: 'b', value: 2 }, { key: 'c', value: 3 } ]

Input:
{ name: "John", age: 30, city: "New York" }
Output: [ { key: 'name', value: 'John' }, { key: 'age', value: 30 }, { key: 'city', value: 'New York' } ]

Input:
{}
Output: []

💡 Approach:
✅ Step 1: Use Object.entries() to extract key-value pairs as an array.
✅ Step 2: Use the map() method to transform the array into an array of objects.
✅ Step 3: Destructure each key-value pair inside the map() loop.
✅ Step 4: Return the final array of objects.

📚 Key Concepts Used:
✅ Object.entries(): Converts an object into an array of key-value pairs.
✅ Array.prototype.map(): Iterates and transforms elements of an array.
✅ Destructuring: [key, value] to directly extract elements from an array.

📅 On Day 86, you learned how to transform an object into an array of objects containing key-value pairs using Object.entries() and the map() method.

🔥 Keep coding and stay consistent!
