I’ve solved Everything Be True after switching from dot notation to bracket notation, but I don’t understand why. Specifically, this line was failing:
if(!collection[i].pre){ return false; }
But when I changed it to bracket notation, my code passed:
if(!collection[i][pre]) { return false; }
I’ve looked up the differences between bracket and dot notation and both should work in this scenario. I’m missing something why the dot notation isn’t working - what could it be?
Your code so far
function truthCheck(collection, pre) {
// Is everyone being true?
for(i = 0; i < collection.length; i++) {
if(!collection[i].hasOwnProperty(pre)) { return false; }
if(!collection[i].pre) { return false; }
}
return true;
}
truthCheck([{"user": "Tinky-Winky", "sex": "male"}, {"user": "Dipsy", "sex": "male"}, {"user": "Laa-Laa", "sex": "female"}, {"user": "Po", "sex": "female"}], "sex");
