javascript array entries is a built-in method that returns an iterator object with key-value pairs representing array indexes and their corresponding values. This is particularly useful when looping through arrays.
Example:
javascript
Copy
Edit
const fruits = ["apple", "banana", "cherry"];
const iterator = fruits.entries();
for (let entry of iterator) {
console.log(entry);
}
// Output:
// [0, "apple"]
// [1, "banana"]
// [2, "cherry"]
Benefits of Using entries()
Allows iteration with both index and value.
Compatible with for...of loops for cleaner code.
Helps in managing key-value relationships within arrays
