Problem with bug

Tell us what’s happening:
Please what is wrong with my if…else statement?.
It should return false if emp and arr has an element in common. But it is doing the opposite.
Your code so far

function truthCheck(collection, pre) {
var emp=[];
var arr=["", undefined, null, 0, false, []];

for(let i=0; i<emp.length; i++){
  for(let j=0; j<arr.length; j++){
      var result=true
    }else if(emp[i]===arr[j]){
      var result=false
return result

console.log(truthCheck([{"user": "Tinky-Winky"}, {"user": "Dipsy", "sex": "male"}, {"user": "Laa-Laa", "sex": "female"}, {"user": "Po", "sex": "female"}], "sex"));

Challenge: Everything Be True

Link to the challenge:

this will give the result for whatever last values i and j have, so your code is at the end checking only the last one, not all of them

This is a better alternative then how you are using arr
This will work similarly, but make sure you read the docs to understand the difference

please how do i make it check everything?

helpful. thank you for the link

This will work wih your current use of arr

You will however need to use: Number.isNaN() - JavaScript | MDN as (NaN === NaN) would be false.
