Exercise #4

Write a function welcome that:

Takes two parameters name1 and name2

var welcome = ???? // TODO

var result = welcome('Alice', 'Bob');
console.log('Result should be "Welcome, Alice and Bob!"', result);

var result = welcome('Alice');
console.log('Result should be "Welcome, Alice!"', result);
