+
+The **`entries()`** method returns a new array iterator object that contains key/value pairs for each index in the array. This is useful when both the index and value of array elements are needed during iteration.
+
+## Syntax
+
+```pseudo
+array.entries()
+```
+
+**Parameters:**
+
+The `entries()` method does not take any parameters.
+
+**Return value:**
+
+A new `Array Iterator` object containing `[index, value]` pairs
+
+## Example
+
+In this example the `.entries()` method is used to iterate over an array of cat names, accessing both the index and value in each loop:
+
+```js
+const cats = ['Peche', 'Moana', 'Pintassilga'];
+const iterator = cats.entries();
+
+for (let [index, name] of iterator) {
+  console.log(`Cat #${index}: ${name}`);
+}
+```
+
+The output of this code is:
+
+```shell
+Cat #0: Peche
+Cat #1: Moana
+Cat #2: Pintassilga
+```
+
+## Codebyte Example
+
+In this example the loop prints each index and corresponding fruit name by iterating through the key/value pairs returned by `.entries()`:
+
+```codebyte/javascript
+const fruits = ['apple', 'banana', 'cherry'];
+const iterator = fruits.entries();
+
+for (let [index, fruit] of iterator) {
+  console.log(index, fruit);
+}
+```
