A functional programming library for PHP, inspired by Ramda.js. Slash provides a set of utilities to help you write cleaner, more maintainable code using functional programming principles.

## Quick Examples

### Array Transformation
```php
<?php
// Map: Transform each element in an array
slash()->map([1, 2, 3], fn($n) => $n * 2);  // [2, 4, 6]

// Filter: Keep only elements that pass a test
slash()->filter([1, 2, 3, 4, 5], fn($n) => $n % 2 === 0);  // [2, 4]

// Reduce: Combine all elements into a single value
slash()->reduce([1, 2, 3, 4], fn($acc, $n) => $acc + $n, 0);  // 10
```

### Data Manipulation
```php
<?php
// Group data by a property
$records = [
    ["id" => 1, "value1" => 5, "value2" => 10],
    ["id" => 1, "value1" => 1, "value2" => 2],
    ["id" => 2, "value1" => 50, "value2" => 100],
    ["id" => 2, "value1" => 15, "value2" => 20],
    ["id" => 3, "value1" => 15, "value2" => 20]
];

$grouped = slash()->groupBy($records, 'id');
/*
Result:
[
    1 => [
        ["id" => 1, "value1" => 5, "value2" => 10],
        ["id" => 1, "value1" => 1, "value2" => 2]
    ],
    2 => [
        ["id" => 2, "value1" => 50, "value2" => 100],
        ["id" => 2, "value1" => 15, "value2" => 20]
    ],
    3 => [
        ["id" => 3, "value1" => 15, "value2" => 20]
    ]
]
*/
```

### Utility Functions
```php
<?php
// Find maximum value
slash()->max([1, 2, 3]);  // 3

// Flatten nested arrays
slash()->flatten([1, [2, [3]]]);  // [1, 2, 3]

// Get last elements
slash()->last([1, 2, 3, 4, 5], 2);  // [4, 5]

// Check if all elements satisfy a condition
slash()->all([1, 3, 5], fn($n) => $n % 2 === 1);  // true (all are odd)

// Check if any element satisfies a condition
slash()->any([1, 2, 3], fn($n) => $n > 2);  // true
```
## Why Slash?

There are already several excellent libraries with a functional flavor. Typically, they are meant to be general-purpose toolkits, suitable 
for working in multiple paradigms. Slash has a more focused goal. We wanted a library designed specifically for a functional programming style, 
one that makes it easy to create functional pipelines, one that never mutates user data.

## What's Different?
The primary distinguishing features of slash are:

Slash emphasizes a purer functional style. Immutability and side-effect free functions are at the heart of its design philosophy. This can help you get the job done with simple, elegant code.

Slash functions are automatically curried. This allows you to easily build up new functions from old ones simply by not supplying the final parameters.

The parameters to Slash functions are arranged to make it convenient for currying. The data to be operated on is generally supplied last.

The last two points together make it very easy to build functions as sequences of simpler functions, each of which transforms the data and passes it along to the next. Slash is designed to support this style of coding.

## Install
Requires PHP 8+
```bash
composer require masterfermin02/slash
```

## Usage
Slash operations are pure functions that can be used alone.

## Functional Programming with Slash

Slash makes it easy to write functional code in PHP. Here are some more advanced examples:

### Function Composition

```php
<?php
// Create a pipeline of operations
$processData = slash()->pipeLine(
    slash()->mapWith(fn($x) => $x * 2),
    slash()->filterWith(fn($x) => $x > 5),
    slash()->sortBy(fn($a, $b) => $a - $b)
);

$result = $processData([1, 4, 2, 5]);
// Result: [6, 8, 10]
```

### Working with Objects

```php
<?php
// Extract and transform properties from objects
$products = [
    (object)['id' => 1, 'name' => 'Laptop', 'price' => 1000],
    (object)['id' => 2, 'name' => 'Phone', 'price' => 500],
    (object)['id' => 3, 'name' => 'Tablet', 'price' => 300],
];

$discountedPrices = slash()->map(
    $products,
    fn($product) => [
        'name' => $product->name,
        'price' => $product->price * 0.9 // 10% discount
    ]
);
```
