### similarity
|
|
|
|
Returns an array of elements that appear in both arrays.
|
|
|
|
Use `filter()` to remove values that are not part of `values`, determined using `includes()`.
|
|
|
|
```js
|
|
const similarity = (arr, values) => arr.filter(v => values.includes(v));
|
|
```
|
|
|
|
```js
|
|
similarity([1,2,3], [1,2,4]) -> [1,2]
|
|
```
