## Arrays
By default, only the array itself is cloned (shallow), use [clone-deep](https://github.com/jonschlinkert/clone-deep) if you also need the elements in the array to be cloned.
```js
const arr = [{ a: 0 }, { b: 1 }];
const foo = clone(arr);
// foo => [{ 'a': 0 }, { 'b': 1 }]
// array is cloned
assert(actual === expected); // false
// array elements are not
assert.deepEqual(actual[0], expected[0]); // true
```
## Objects
Only the object is shallow cloned, use [clone-deep](https://github.com/jonschlinkert/clone-deep) if you also need the values in the object to be cloned.
```js
console.log(clone({ a: 1, b: 2, c: 3 }));
//=> {a: 1, b: 2, c: 3 }
```
## RegExp
Clones regular expressions and flags, and preserves the `.lastIndex`.
```js
const regex = clone(/foo/g); //=> /foo/g
// you can manually reset lastIndex if necessary
regex.lastIndex = 0;
```
## Primitives
Simply returns primitives unchanged.
```js
clone(0); //=> 0
clone('foo'); //=> 'foo'
```
