### 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
|
|
```
