Source: https://gitlab.com/upstash/context7test/-/blob/main/docs/api.md

Dart example mapping over a list and printing the result.

### TypeScript: Typed User Model and Formatting

Source: https://gitlab.com/upstash/context7test/-/blob/main/docs/guide.md

Demonstrates TypeScript's type safety with a user interface and a function to format user information. Use this for examples of strong typing in TypeScript.

```typescript
interface User { id: number; name: string; active: boolean }
function formatUser(u: User): string { return `${u.id}:${u.name}:${u.active}` }
console.log(formatUser({ id: 1, name: 'Ada', active: true }));
```

### Go: Minimal HTTP Server

Source: https://gitlab.com/upstash/context7test/-/blob/main/docs/guide.md

A basic HTTP server in Go that responds with a greeting. It illustrates the usage of the net/http package for creating simple web services.

```go
package main
import (
    "fmt"
    "net/http"
)
func main(){
    http.HandleFunc("/", func(w http.ResponseWriter, r *http.Request){
        fmt.Fprintln(w, "Hello from Go!")
    })
    http.ListenAndServe(":8080", nil)
}
```

### Julia: Generate Cubes using List Comprehension

Source: https://gitlab.com/upstash/context7test/-/blob/main/README.md

Generates a list of cubes for numbers in a given range using Julia's list comprehension syntax. Prints the resulting list.

```julia
nums = 1:5
cubes = [n^3 for n in nums]
println(cubes)
```

### C#: LINQ Query for Filtering and Projection

Source: https://gitlab.com/upstash/context7test/-/blob/main/docs/guide.md

Filters and projects a sequence of numbers using C# LINQ to demonstrate expressive collection manipulation. This is useful for showcasing LINQ's capabilities.

```csharp
using System;
using System.Linq;
class Program {
  static void Main(){
    var nums = new[]{1,2,3,4,5};
    var squares = nums.Where(n=>n%2==1).Select(n=>n*n);
    Console.WriteLine(string.Join(",", squares));
  }
}
```

### Bash: Count Files in Current Directory

Source: https://gitlab.com/upstash/context7test/-/blob/main/README.md

Counts the number of files in the current directory using `ls` and `wc -l`. Outputs the count prefixed with 'Files: '.

```bash
FILES=$(ls | wc -l)
echo "Files: $FILES"
```

### PHP: JSON Response

Source: https://gitlab.com/upstash/context7test/-/blob/main/docs/api.md

Outputs a JSON response in PHP for a simple API endpoint. Illustrates header setting and encoding.

```php
<?php
header('Content-Type: application/json');
echo json_encode(['status' => 'ok', 'time' => time()]);

```

### Haskell: Filter Odd Numbers and Square Them

Source: https://gitlab.com/upstash/context7test/-/blob/main/README.md

Filters a list of numbers to keep only odd ones, then squares each of them. Prints the resulting list.

```haskell
main :: IO ()
main = print $ map (^2) $ filter odd [1..10]
```
