# Get Query Parameter Input from the Client
|
|
|
|

|
|
## Problem Explanation
|
|
|
|
Given the endpoint URL, `/name?first=firstname&last=lastname`, we can extract the query parameters (`first` and `last`) and their corresponding values from the `req.query` object and send a custom JSON response containing values derived from the query parameters to the client.

```javascript
|
|
app.get("/name", function(req, res) {
|
|
var firstName = req.query.first;
|
|
var lastName = req.query.last;
|
|
// OR you can destructure and rename the keys
|
|
var { first: firstName, last: lastName } = req.query;
|
|
// Use template literals to form a formatted string
|
|
res.json({
|
|
name: `${firstName} ${lastName}`
|
|
});
|
|
});
|
|
```
