> Learn how to use the get() method to get an element from a Map object in JavaScript.

The `get()` method is used to retrieve an element from a `Map` object in JavaScript. This method accepts the key of the element as an argument and returns the associated value. If the key is not found in the `Map`, it returns `undefined`.

```javascript
const map = new Map()

map.set('name', 'John Doe')
map.set('age', 29)
map.set('job', 'UX Designer')

console.log(map.get('name')) // John Doe
console.log(map.get('age')) // 29
console.log(map.get('job')) // UX Designer

console.log(map.get('address')) // undefined
```

If the value associated with the specified key is an object, the `get()` method returns a reference to that object. Any modifications made to the object will be reflected inside the `Map` object as well:

```javascript
const product = { name: 'Milk', qty: 2 }
const prices = [2.99]

const items = new Map()
items.set('product', product)
items.set('prices', prices)

items.get('product').qty = 100
items.get('prices').push(4.55)

console.log(product)
// { name: 'Milk', qty: 100 }

console.log(prices)
// [ 2.99, 4.55 ]
```
