Tell us what’s happening:
On the last if statement, when I change the conditions around(falseCount===0 and falseCount>0), the completed Ii had become grey and the other one are ticked. Why is that, if the statement still covers both conditions?
Your code so far
function truthCheck(collection, pre) {
for (let i = 0; i < collection.length; i++) {
for (let key in collection[i]) {
var falseCount=0;
if (collection[i].hasOwnProperty(key)) {
console.log("checking " + JSON.stringify(collection[i]));
if (collection[i][pre]) {
console.log("this is true!");
} else {
console.log("this is false!");
falseCount++;
console.log("falseCount is " + falseCount);
}
}
}
if (falseCount=0) {
return true;
} else {
return false;
}
}
}
truthCheck([{"user": "Tinky-Winky", "sex": "male"}, {"user": "Dipsy", "sex": "male"}, {"user": "Laa-Laa", "sex": "female"}, {"user": "Po", "sex": "female"}], "sex");

The code you posted above only checks the first object in the array, before returning a true or false value. The following if statement is actually assigning a value of 0 to falseCount and then evaluating the if statement as if (0) {, so the else block of code will always execute. You should be comparing falseCount to zero with the === operator if you want to return true when falseCount is zero.
I do not exactly understand what code you tried, so if you want to post the exact if statement you tried, then I can see what you meant in the above question.
Nevermind, I figured out that specific statement I believe. I moved the if statement until after the for loop. Now, I think that if falseCount is anything other than zero, it should return false. But from the console, I can’t really see why e few of them return the wrong thing. They also appear twice for some reason. Here is my code:
function truthCheck(collection, pre) {
for (let i = 0; i < collection.length; i++) {
for (let key in collection[i]) {
var falseCount=0;
if (collection[i].hasOwnProperty(key)) {
console.log("checking " + JSON.stringify(collection[i]));
if (collection[i][pre]) {
console.log("this is true!");
} else {
console.log("this is false!");
falseCount++;
console.log("falseCount is " + falseCount);
} else if (!collection[i].hasOwnProperty(pre)) {
return false;
}
}
}
}
if (falseCount===0) {
return true;
} else {
return false;
}
}
truthCheck([{"user": "Tinky-Winky", "sex": "male"}, {"user": "Dipsy", "sex": "male"}, {"user": "Laa-Laa", "sex": "female"}, {"user": "Po", "sex": "female"}], "sex");
