Supports
By default, only the array itself is cloned (shallow), use 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 ```
Only the object is shallow cloned, use 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 }
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;
Simply returns primitives unchanged.
js
clone(0); //=> 0
clone('foo'); //=> 'foo'
