guard let reachability = Reachability(), reachability.isReachable == true else {
    // No network connection available. Do stuff.
    ...
}

While this works, it's not immediately readable and creates confusion. Mis-using Swift's control flow. Did not pass code review.

	Yes = 0,
	No = 1

I also like how they defined the enum values.

let foo = {} // object no. 1

foo == bar // oh well, return false

foo >= bar // return true, 'cause !(foo < bar) == true

return value is expected, but JS is funny

I found this old code in an app I was updating for a client a number of years back. It was so good I documented it on my own blog.

const ITEM_COUNT = 100
let visibleItems = []
for (let i = 0; i < ITEM_COUNT; ++i) {
  visibleItems.push(false)
}

function showItem(index) {
  visibleItems = []
  for (let i = 0; i < ITEM_COUNT; ++i) {
    visibleItems.push(false)
  }
  visibleItems[index] = true
}

It was more or less like this. The guy had a collection of React components and wanted to show only one of them at a time. Instead of storing the index of the component to show at the moment, he decided that a boolean array would work much better. O(n) in runtime and space and null readability just because.
