Kata

Create a variable and then compare it in a switch statement then output the results to the console.

    var result: string = 'dog';

    switch (result) {
        case 'cat':
            {
                console.log('a cat was chosen');
            }
        case 'dog':
            {
                console.log('a dog was chosen');
            }
    }
    Create another switch statement but add a “default”.

    switch (result) {
        case 'cat': {
            console.log('a cat was chosen');
        }
        case 'bird': {
            console.log('a bird was chosen');
        }
        default: {
            console.log('the default was used.');
        }
    }
