While this works, it's not immediately readable and creates confusion. Mis-using Swift's control flow. Did not pass code review.
public enum YesNoEnum
{
Yes = 0,
No = 1
}
I also like how they defined the enum values.
boolean darkModeSelected = (!darkModeSelected ? true : false);
if (i === 1 || i === 2 || i === 3 || i === 4 || i === 5 || i === 6 || i === 7 || i === 8 || i === 9 || i === 10){
return true;
}
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

use while as if!!!!

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.
