[Radel Vanox]

Подскажите как можно улучшить следующий

switch(err) {
                                                        case "BrowserNotSupported":
                                                                showMessage("Your browser does not support HTML5 file uploads!");
                                                                break;
                                                        case "TooManyFiles":
                                                                alert("Too many files! Please select 5 at most! (configurable)");
                                                                break;
                                                        case "FileTooLarge":
                                                                alert(file.name+" is too large! Please upload files up to 5mb (configurable).");
                                                                break;
                                                        default:
                                                                break;
                                                }

const objError = {
  BrowserNotSupported: "Your browser does not support HTML5 file uploads!",
  TooManyFiles: "Too many files! Please select 5 at most! (configurable)",
  FileTooLarge: `${file.name} is too large! Please upload files up to 5mb (configurable).`
}
alert(objError[err])
