Tests:

  • few over more

     
    var tempResult = fewElements.some(e => moreElements.includes(e))

  • few over more included

     
    var tempResult = fewElements.some(e => moreElementsIncluded.includes(e))

  • more over few

     
    var tempResult = moreElements.some(e => fewElements.includes(e))

  • more over few included

     
    var tempResult = moreElementsIncluded.some(e => fewElements.includes(e))
