@ -5,6 +5,6 @@ Checks if the predicate (second argument) is truthy on all elements of a collect
Use `Array.every()` to check if each passed object has the specified property and if it returns a truthy value.
```js
truthCheckCollection = (collection, pre) => (collection.every(obj => obj[pre]));
const truthCheckCollection = (collection, pre) => (collection.every(obj => obj[pre]));
// truthCheckCollection([{"user": "Tinky-Winky", "sex": "male"}, {"user": "Dipsy", "sex": "male"}], "sex") -> true
```
