What does the following code alert?

var person = {
name: "Mike",
age: 25,
favoriteFood: "pizza"
};

It is just a declaration of an object variable, person, in JavaScript. Within a person object, there are key:value pairs. The code that you shared has the following keys: name, age, and favouriteFood, whereas the values of those keys are: Mike, 25, and pizza.

There is no alert statement in this code snippet; therefore, it will not alert anything. This code contains only a variable called person, and that's it!
