Regarding to the Mongoose-Documentation, your way is correct.

Here a small example:

var arrayTestSchema = new Schema({
    anArray: {
      type: Array,
      'default': [1, 2, 3]
    }
});

And a link to the related documentation page: http://mongoosejs.com/docs/2.7.x/docs/defaults.html

for Mongoose v5.x

If you want to specify the type of the array child, you can define it like example below:

const BlogSchema = new Schema({
  tags: {
    type: [String],
    default: ["tech", "economy"],
  },
})

or

const BlogSchema = new Schema({
  tags: {
    type: [
      {
        type: String,
        // Another properties
      },
    ],
    default: ["tech", "economy"],
  },
})

It should be a json, I don't know what is what you posted there.

new Schema({ warning: { type: Array, default: [10, 50, 99] } })
