Data Structure challenge (Everything but true) doesn't pass on a correct solution

JavaScript
#1

The tests of that challenge https://www.freecodecamp.org/learn/javascript-algorithms-and-data-structures/intermediate-algorithm-scripting/everything-be-true doesn’t pass on what looks like a correct solution :

function truthCheck(collection, pre) {
  return collection.every(function(element) {
    return element.hasOwnProperty(pre) && Boolean(element.pre);
  });
}

but passes on this solution :

function truthCheck(collection, pre) {
  return collection.every(function(element) {
    return element.hasOwnProperty(pre) && Boolean(element[pre]);
  });
}

I was using Chrome as a browser in a ubuntu 20 machine

Tests cases that fail are indeed returning wrong result, so there’s something not right in function.

Take a closer look at the function in every method, check what both parts in the return statement produce and if that’s what is expected.

#3

you can’t use dot notation to access object properties with variables, element.pre is always undefined because the objects do not have a pre property

I’ve edited your post for readability. When you enter a code block into a forum post, please precede it with a separate line of three backticks and follow it with a separate line of three backticks to make it easier to read.

You can also use the “preformatted text” tool in the editor (</>) to add backticks around text.

See this post to find the backtick on your keyboard.
Note: Backticks (`) are not single quotes (’).
