Yes, this is JavaScript, and yes it didn't work. Found while reviewing some code

let foo = {} // object no. 1
let bar = {} // object no. 2

foo > bar // return false
foo < bar // return false, so maybe foo equals bar?
foo == bar // oh well, return false
// but
foo >= bar // return true, 'cause !(foo < bar) == true

return value is expected, but JS is funny

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.
