+## Description
+
+The `entries()` method returns a new Array Iterator object that contains the key/value pairs for each index in the array. It allows you to loop through both the **index** and the **value** of each element in a structured way.
+
+## Syntax
+
+```javascript
+array.entries()
+```
+
+## Parameters
+
+This method does **not** take any parameters.
+
+## Return Value
+
+Returns a new Array Iterator object that can be used in a `for...of` loop or manually.
+
+## Examples
+
+```javascript
+const cats = ['Peche', 'Moana', 'Pintassilga'];
+const iterator = cats.entries();
+
+for (let [index, name] of iterator) {
+  console.log(`Cat #${index}: ${name}`);
+}
+
+// Output:
+// Cat #0: Peche
+// Cat #1: Moana
+// Cat #2: Pintassilga
+```
+
+## Codebyte
+
+```codebyte/javascript
+const fruits = ['apple', 'banana', 'cherry'];
+const iterator = fruits.entries();
+
+for (let [index, fruit] of iterator) {
+  console.log(index, fruit);
+}
+```
+
+## Notes
+
+- Often used with `for...of` loops.
+- Helpful when both the index and value of elements are needed.
+- The iterator object returned can also be converted using `Array.from()`.
