### truthCheckCollection

Checks if the predicate (second argument) is truthy on all elements of a collection (first argument).

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]));
// truthCheckCollection([{"user": "Tinky-Winky", "sex": "male"}, {"user": "Dipsy", "sex": "male"}], "sex") -> true
```
