    that works correctly, you should write "const" correctly in the naming of the function.

    To capitalize the first letter of a passenger’s name in JavaScript, you can use the following function:

    const capitalizePassengerName = function (name) {
  const passengerName = name.toLowerCase();
  const passengerCorrectName =
    passengerName.charAt(0).toUpperCase() + passengerName.slice(1);
  console.log(passengerCorrectName);
};

capitalizePassengerName("fAdi"); // Output: Fadi

    In this function, we first convert the entire passenger name to lowercase using toLowerCase(). Then, we capitalize the first letter using charAt(0).toUpperCase() and concatenate it with the rest of the lowercase name using slice(1). This will correctly capitalize the name, resulting in "Fadi" as the output.
