Please consider following this project's author, [Jon Schlinkert](https://github.com/jonschlinkert), and consider starring the project to show your :heart: and support. ## Install Install with [npm](https://www.npmjs.com/): ```sh $ npm install --save shallow-clone ``` ## Usage ```js const clone = require('shallow-clone'); ``` **Supports** * array buffers * arrays * buffers * dates * errors * float32 arrays * float64 arrays * int16 arrays * int32 arrays * int8 arrays * maps * objects * primitives * regular expressions * sets * symbols * uint16 arrays * uint32 arrays * uint8 arrays * uint8clamped arrays ## 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' ``` ## About
