Working with an array: getting full names, summing salaries, and searching by last name

There is an array of objects, each containing a character's name, gender, surname, and salary. The task is to perform three operations: create an array of strings where each value is the full name (name + space + surname), calculate the total sum of all salaries, and output a list of all records where the surname matches "Rose".

const data = [
    {
        "charname": "John",
        "gender": "Male",
        "surname": "Rose",
        "salary": 100
    },
    {
        "charname": "Margo",
        "gender": "Female",
        "surname": "Rose",
        "salary": 1200
    },
    {
        "charname": "Lisa",
        "gender": "Male",  // Possibly a typo? Should it be "Female"?
        "surname": "Barcley",
        "salary": 1600
    }
];
