$collection = collect([1, 2, 3]);

            ["id" => 1, "name" => "Sanjay", "email" => "sanjay@gmail.com"],
            ["id" => 2, "name" => "Vijay", "email" => "vijay@gmail.com"],
            ["id" => 3, "name" => "Ashish", "email" => "ashish@gmail.com"]
        ]);

            ["id" => 3, "name" => "Ashish", "email" => "ashish@gmail.com"]
        ]);

        $first = $data->firstWhere("email", "vijay@gmail.com");

    }
}

        $data = collect([
            ["id" => 1, "name" => "Sanjay", "email" => "sanjay@example.com", "age" => 29],
            ["id" => 2, "name" => "Vijay", "email" => "vijay@gmail.com", "age" => 32],
            ["id" => 3, "name" => "Ashish", "email" => "ashish@sample.com", "age" => 25]
        ]);

        $first = $data->firstWhere("age", ">", 30);

        dd($first);
