Inverse of [].filter in JS?

Question

I realize that I can do: ``` arr = arr.filter(function(n){ return !filterFunc(n); }); ``` But is there any way to just invert a filter without wrapping the filterer in an anon function? It just seems cumbersome.

Accepted Answer

You can use an arrow function:

```
const a = someArr.filter(someFilter);
const a = someArr.filter(e => !someFilter(e));
```
