To add spaces between array items in JavaScript, we use the join method.

For instance, we write

const showtimes = ["1pm", "2pm", "3pm"];
const showtimesAsString = showtimes.join(", ");

to call showtimes.join with ', ' as the delimiter between each string in showtimes.

Therefore, showtimesAsString is "1pm, 2pm, 3pm".
