## 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'
|
||||
```
