They are widely studied in number theory and often appear in math puzzles, programming challenges, and teaching exercises.\n\n### Examples\n\n18 is a Harshad number because 1 + 8 = 9 and 18 % 9 === 0.\n\n19 is not, because 1 + 9 = 10 and 19 % 10 !== 0\n\n### Possible workarounds\n\n_No response_\n\n### Additional information\n\n_No response_","author":{"url":"https://github.com/ridge-kimani","@type":"Person","name":"ridge-kimani"},"datePublished":"2025-09-24T18:31:22.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":2},"url":"https://github.com/1802/JavaScript/issues/1802"}
