checkedArr.includes(false) ? false : true
Enter fullscreen mode Exit fullscreen mode

is equivalent to:

! checkedArr.includes(false)
Enter fullscreen mode Exit fullscreen mode

It's like something verbose.

And , here another way:

const truthCheck = (collection, pre) =>
  collection.every(
    e => e[pre]
  )
Enter fullscreen mode Exit fullscreen mode
