# @babel/plugin-transform-destructuring
|
|
|
|
> Compile ES2015 destructuring to ES5
|
|
|
|
## Examples
|
|
|
|
**In**
|
|
|
|
```javascript
|
|
let arr = [1,2,3];
|
|
let {x, y, z} = arr;
|
|
```
|
|
|
|
**Out**
|
|
|
|
```javascript
|
|
var arr = [1, 2, 3];
|
|
var x = arr.x,
|
|
y = arr.y,
|
|
z = arr.z;
|
|
```
|
|
|
|
## Installation
|
|
|
|
```sh
|
|
npm install --save-dev @babel/plugin-transform-destructuring
|
|
```
|
|
|
|
## Usage
|
|
|
|
### Via `.babelrc` (Recommended)
|
|
|
|
**.babelrc**
|
|
|
|
```json
|
|
{
|
|
"plugins": ["@babel/plugin-transform-destructuring"]
|
|
}
|
|
```
|
|
|
|
### Via CLI
|
|
|
|
```sh
|
|
babel --plugins @babel/plugin-transform-destructuring script.js
|
|
```
|
|
|
|
### Via Node API
|
|
|
|
```javascript
|
|
require("@babel/core").transform("code", {
|
|
plugins: ["@babel/plugin-transform-destructuring"]
|
|
});
|
|
```
|
|
|
|
## Options
|
|
|
|
### `loose`
|
|
|
|
`boolean`, defaults to `false`.
|
|
|
|
Enabling this option will assume that what you want to destructure is an array and won't use `Array.from` on other iterables.
|
|
|
|
### `useBuiltIns`
|
|
|
|
`boolean`, defaults to `false`.
|
|
|
|
Enabling this option will use `Object.assign` directly instead of the Babel's `extends` helper.
|
|
|
|
##### Example
|
|
|
|
**.babelrc**
|
|
|
|
```json
|
|
{
|
|
"plugins": [
|
|
["@babel/plugin-transform-destructuring", { "useBuiltIns": true }]
|
|
]
|
|
}
|
|
```
|
|
|
|
**In**
|
|
|
|
```js
|
|
var { ...x } = z;
|
|
```
|
|
|
|
**Out**
|
|
|
|
```js
|
|
var _z = z,
|
|
x = Object.assign({}, _z);
|
|
```
