### Rust: Read Lines from Stdin

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

Reads lines from standard input and echoes them back in Rust. This example highlights ownership-light IO usage.

```rust
use std::io::{self, BufRead};
fn main(){
    let stdin = io::stdin();
    for line in stdin.lock().lines() {
        println!("{}", line.unwrap());
    }
}
```

### R Vector Squaring

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

A simple R example that creates a vector of numbers from 1 to 5 and then computes the square of each element. The result is then printed. This showcases basic vector operations in R.

```r
nums <- 1:5
squares <- nums^2
print(squares)
```

### Swift Map and Filter on Arrays

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

Demonstrates Swift's map and filter methods for concise array transformations. It filters an array of numbers to get even numbers and then doubles them.

```swift
let nums = [1,2,3,4,5]
let evensDoubled = nums.filter { $0 % 2 == 0 }.map { $0 * 2 }
print(evensDoubled)
```

### Julia: List Comprehension for Cubes

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

Generates cubes of numbers in a given range using Julia's list comprehension syntax. This demonstrates concise data transformation.

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

### Kotlin Data Class Copy

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

Demonstrates Kotlin data classes and the copy method for immutable-style updates. It defines a User data class and shows how to create a modified copy of an instance.

```kotlin
data class User(val id:Int, val name:String, val active:Boolean)
fun main(){
  val u1 = User(1, "Ada", true)
  val u2 = u1.copy(active = false)
  println(u2)
}
```

### JavaScript Array Summation using Reduce

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

This snippet demonstrates summing the numbers in an array using JavaScript's reduce method. It showcases a concise, functional approach. The input is an array of numbers, and the output is their sum.

```javascript
const nums = [1, 2, 3, 4, 5];
const total = nums.reduce((acc, n) => acc + n, 0);
console.log(total);
```

### Scala List Filtering and Mapping

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

Demonstrates filtering and mapping a list using Scala's collection pipeline. It takes a list of numbers, filters for odd numbers, squares them, and prints the result. No external dependencies are required.

```scala
object Main {
  def main(args: Array[String]): Unit = {
    val nums = List(1,2,3,4,5)
    val oddsSquared = nums.filter(_ % 2 == 1).map(n => n*n)
    println(oddsSquared)
  }
}
```
