### allBy
|
|
|
|
Returns `true` if the provided predicate function returns `true` for all elements in a collection, `false` otherwise.
|
|
|
|
Use `Array.every()` to test if all elements in the collection return `true` based on `fn`.
|
|
|
|
```js
|
|
const allBy = (arr, fn) => arr.every(fn);
|
|
```
|
|
|
|
```js
|
|
allBy([4, 2, 3], x => x > 1); // true
|
|
```
