Find document with array that contains a specific value

Question

If I have this schema...

person = {
    name : String,
    favoriteFoods : Array
}

... where the favoriteFoods array is popula

Answer 1

As favouriteFoods is a simple array of strings, you can just query that field directly:

PersonModel.find({ favouriteFoods: "sushi" }, ...);

But I'd also recommend making the string array explicit in your schema:

person = {
    name : String,
    favouriteFoods : [String]
}
