$collection = collect([1, 2, 3, 4, 5]);
$filtered = $collection->reject(function ($item) {
    return $item % 2 == 0; // Exclude even numbers
dd($filtered->all()); // Output: [1, 3, 5]
    
$collection = collect([1, 2, 3, 4, 5]);
$squared = $collection->map(function ($item) {
    return $item * $item; // Square each number
dd($squared->all()); // Output: [1, 4, 9, 16, 25]
    
In summary, while reject is your tool for excluding items, map is your friend for transforming them. Choose the right function based on your data manipulation needs.
Happy coding! 🚀
