Problem 9. Play with Number, Boolean and String

// Write a program that, depending on the user’s choice, inputs a number, boolean or string variable.
// * If the variable is number, the program increases it by one. * If the variable is boolean,
// the program swaps it with its counterpart. * If the variable is a string,
// the program appends * at the end. * Print the result at the console. Use switch statement.

let input = ['1', '3'];
let print = this.print || console.log;
let gets = this.gets || ((arr, index) => () => arr[index++])(input, 0);

let userChoice = +gets();
let userInput = gets();

switch (userChoice) {
    case 1:
        print(`Please enter a number: ${userInput}`);
        print(`${Number(userInput) + 1}`);

        break;
    case 2:
        print(`Please enter a boolean: ${userInput}`);
        print(!userInput);
        break;
    case 3:
        print(`Please enter a string: ${userInput}`);
        print(`${userInput}*`);

        break;

    default:
        break;
}
