I am having trouble getting a line break into string interpolation that is printed out in my HTML

this.externalUsers = data.externalUser.map(element => `Name: ${element.firstName} ${element.lastName}\n <br><br />Email: ${element.email}`);

In the line above I am trying to get the first and last name on one line and email on the next

<v-radio 
  v-for="item in externalUsers" 
  :key="item.id"
  :label="item"
  :value="item"
></v-radio>

I am using Vue so I am printing it out with a for a loop.

Here is the result

You can use white-space: pre-line; as follows:

new Vue({
  el:"#app",
  vuetify: new Vuetify(),
  data: () => ({
    externalUser: [
      { firstName: 'firstName1', lastName: 'lastName1', email: 'email1' },
      { firstName: 'firstName2', lastName: 'lastName2', email: 'email2' },
      { firstName: 'firstName3', lastName: 'lastName3', email: 'email3' },
    ]
  }),
  computed: {
    externalUsers() {
      return this.externalUser.map(element => 
        `Name: ${element.firstName} ${element.lastName}\nEmail: ${element.email}`);
    }
  }
});
#app { white-space: pre-line; }
