# \$1each
<a name="each"></a>

The `$each` operator is used in conjunction with other update operators, such as `$push` and `$addToSet`, to add multiple values to an array field. It allows adding multiple elements to an array in a single operation, rather than having to execute multiple update operations.

**Parameters**
+ `value`: The array of values to add to the array field.

## Example (MongoDB Shell)
<a name="each-examples"></a>

The following example demonstrates using the `$each` operator with the `$push` operator to add multiple elements to an array field.

**Create sample documents**

```
db.fruits.insertOne({
  _id: 1,
  fruits: ["apple", "banana"]
})
```

**Query example**

```
db.fruits.updateOne(
  { _id: 1 },
  { $push: { fruits: { $each: ["cherry", "durian", "elderberry"] } } }
)
```

**View updated document**

```
db.fruits.findOne({ _id: 1 })
```

**Output**

```
{
  _id: 1,
  fruits: [ 'apple', 'banana', 'cherry', 'durian', 'elderberry' ]
}
```
