shallow-clone

    0.1.2 • Public • Published

    shallow-clone NPM version

    Make a shallow clone of an object, array or primitive.

    Install

    Install with npm

    $ npm i shallow-clone --save

    Usage

    var clone = require('shallow-clone');

    shallow clones arrays

    The array itself is cloned, but not the elements of the array. So any objects in the array will still not be cloned (e.g. they will be the same object as in the orginal array).

    var arr = [{ 'a': 0 }, { 'b': 1 }]
    var foo = clone(arr);
    // foo =>  [{ 'a': 0 }, { 'b': 1 }]
     
    // array is cloned
    assert.equal(actual === expected, false);
     
    // array elements are not
    assert.deepEqual(actual[0], expected[0]); // true

    returns primitives as-is

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

    shallow clone a regex

    clone(/foo/g)
    //=> /foo/g

    shallow clone an object

    clone({a: 1, b: 2, c: 3 })
    //=> {a: 1, b: 2, c: 3 }
