Besides var, we now have access to two new identifiers for storing values - let and const. Unlike var, let and const statements are not hoisted to the top of their enclosing scope.

An example of using var:

var snack = 'Meow Mix';

function getFood(food) {
    if (food) {
        var snack = 'Friskies';
        return snack;
    }
    return snack;
}

getFood(false); // undefined
