### Installation

`npm i replace-with -S`  

### Source ([index.js](./index.js))

```js

/**

 * Replace an array|object's content with the other one's while keeping the reference

 * @param  {Array|Object} orig

 * @param  {Array|Object} other

 * @return {Array|Object} orig

 */

var keys = Object.keys;

module.exports = function replaceWith(orig, other) {

  if (Array.isArray(orig)) {

    // for Array

    orig.splice.apply(orig, [0, orig.length].concat(other));

  } else {

    // for Object

    keys(orig).forEach(function (k) { delete orig[k] });

    keys(other).forEach(function (k) { orig[k] = other[k] });

  }

  return orig;

};

```

### Usage

> Let's take a look at the [test examples](./test/index.js)

```js

test('replace array', t => {

  const orig = [1, 2, 3]

  const ref = orig

  replaceWith(orig, [4, 5, 6])

  t.is(ref, orig) // pass!

  t.deepEqual(orig, [4, 5, 6]) // pass!

})

test('replace object', t => {

  let orig = { a: 1, b: 2, c: 3 }

  const ref = orig

  orig = replaceWith(orig, { d: 4, e: 5, f: 6 })

  t.is(ref, orig) // pass!

  t.deepEqual(orig, { d: 4, e: 5, f: 6 }) // pass!

})

```
