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.

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][] if you also need the values in the object to be cloned.

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.

const regex = clone(/foo/g); //=> /foo/g
// you can manually reset lastIndex if necessary
regex.lastIndex = 0;

Primitives

Simply returns primitives unchanged.

clone(0); //=> 0
clone('foo'); //=> 'foo'
