 Use `Array.concat()` to concatenate an array with any additional arrays and/or values, specified in `args`.

+### Array remove
+
+Use `Array.filter()` to find array elements that return truthy values and `Array.reduce()` to remove elements using `Array.splice()`.
+The `func` is invoked with three arguments (`value, index, array`).
+
+```js
+const remove = (arr, func) =>
+  Array.isArray(arr) ? arr.filter(func).reduce((acc, val) => {
+    arr.splice(arr.indexOf(val), 1); return acc.concat(val);
+    }, [])
+  : [];
+//remove([1, 2, 3, 4], n => n % 2 == 0) -> [2, 4]
+```
