Could you have written the functions as arrow functions.... such as

var like = (thing) => `I like ${thing}`;

var love=(thing)=> `I love ${thing}`;

You could even combine both of them into 1 arrow function!

let likeLove = (thing1, thing2) => `I like ${thing1}, but love ${thing2}`;
console.log(likeLove(`beer`, `sleeping`));

Yes! You could do it like this: 

let like = thing => `I like ${thing}!`

Notice that I changed var to let and removed the optional parentheses around the parameter

Is it better practice to use const for functions? (assuming we don't want to overwrite them later)
