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