join(categories; , )
Output: SaaS, Automation, AI
join(array; separator) combines every element into one string, inserting the separator between them. Here the separator is a comma followed by a space.💡 Pro tip: Use newline as the separator to put each item on its own line, which is handy for emails and Slack messages.
