Creates a shallow clone of any JavaScript value.
npm install shallow-clone> Creates a shallow clone of any JavaScript value.
Please consider following this project's author, Jon Schlinkert, and consider starring the project to show your :heart: and support.
Install with npm:
``sh`
$ npm install --save shallow-clone
`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
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'
