This is a critical concept that appears to be poorly understood in at least the web development circles I run in.

It reminds me of one of my favorite Bill Gates quotes:

"The first rule of any technology used in a business is that automation applied to an efficient operation will magnify the efficiency. The second is that automation applied to an inefficient operation will magnify the inefficiency."

Not knowing about a rarely used operator isn't that big of a deal, but the "hard" part of fizzBuzz is trivial in the couple of languages I am proficient in.

In JS:

const isEvenlyDivisible = (num, denominator) => Math.floor(num / denominator) === (num / denominator)

#6 might be the only real chance the US has of having less divisive politics. Moving the upper middle class and wealthy out of cities could change the game entirely by making the political extremes less concentrated geographically.
