Tal vez no le resultó obvio al leer la lección anterior sobre concatenación de cadenas cómo las cadenas resultantes impresas en los cuadros de alerta se imprimían en una sola línea. Si bien esto es aceptable cuando se trabaja con cadenas cortas, la salida de cadenas a menudo será demasiado larga para ser legible en una sola línea.
Recuerde – el carácter de nueva línea sólo creará una interrupción en el código fuente, o en un cuadro de diálogo como en los ejemplos anteriores. El carácter de nueva línea no creará un salto en el HTML renderizado. Para crear un salto de línea en el HTML renderizado, debes usar la etiqueta HTML break (o una similar) en la cadena como si estuvieras escribiendo el código fuente en un editor.

You split the customItems string into an array of strings, then looped through and appended “- ” to the beginning and “\n” to the end of each string in the array. Then you just used .join() to combine the array back into a single string and appended it to the DOM.
Keep in mind that the <br> element has a very specialized purpose. According to MDN, <br> elements are only for adding line breaks in text “where the division of lines is significant” like a poem or a postal address.
