How to save array of strings with Node Mongoose?

To save array of strings with Node Mongoose, we put the data type in an array.

For instance, we write

const personSchema = new mongoose.Schema({
  tags: [
    {
      type: String,
    },
  ],
});

to add the tags field to the personSchema and make it a string array field with

[
  {
    type: String,
  },
];
