Create a `Set` from `b`, then use `Array.filter()` on `a` to only keep values not contained in `b`.
|
||||
|
||||
```js
|
||||
const difference = (a, b) => { const s = new Set(b); return a.filter(x => !s.has(x)); };
|
||||
const difference = (a, b) => {
|
||||
const s = new Set(b);
|
||||
return a.filter(x => !s.has(x));
|
||||
};
|
||||
```
|
||||
|
||||
```js
|
||||
difference([1,2,3], [1,2,4]) // [3]
|
||||
difference([1, 2, 3], [1, 2, 4]); // [3]
|
||||
```
