The Biblical “magi” are not the same as the “Persian clan” referenced in your source. The Biblical word is simply a generic term for “astrologers” or “magicians” but which is rooted in the Persian meaning. In fact, the singular “magus” is used in reference to a Jew who practiced some form of magic in Acts 13:6-8.
The word “magi” is plural for “magus” which means “astrologer”. In the Bible, God condemned all forms of astrology or similar “fortune telling” (e.g. see Deuteronomy 18:10-12). Thus, these astrologers were not some sort of God-ordained “wise men” as many believe. The “star” the astrologers initially followed was for the purpose of leading them and the child to King Herod, who planned to kill the child. God eventually intervened though to foil what was initially an evil plan.
I don’t know anything about using Elm in practice but I’ve been curating a newsletter[1] for front-end developers for almost 10 years now. I often share new scripts, plugins, and tools related to different JavaScript libraries. Over 450 issues later, I think I’ve only shared an Elm-related tool around 4 times. I don’t think Elm is dead, but it’s certainly not something I see come across the literally hundreds of sources I scour every month when curating the newsletter content.
