Sql: One of the most valuable skills

Yes, this was going a little beyond just a basic understanding of SQL… but adding an index to a query instead of rolling my own homegrown caching well that was well worth the extra time learning. Then about 10 years later jQuery came along and while it was a little more verbose at times and something new to learn it made things prettier overall so I committed to re-learning the jQuery approach to JS. Yes we get a new standard every few years and occasionally something new comes along like support for window functions or CTEs, but the basics of SQL are pretty permanent.
