[![Node.js CI](https://github.com/keyz/babel-plugin-transform-optimize-object-literal/workflows/Node.js%20CI/badge.svg)](https://github.com/keyz/babel-plugin-transform-optimize-object-literal/actions "CI Status") [![npm version](http://img.shields.io/npm/v/babel-plugin-transform-optimize-object-literal.svg?style=flat)](https://npmjs.org/package/babel-plugin-transform-optimize-object-literal "View on npm")

Because I heard `JSON.parse` is blazing fast https://v8.dev/blog/cost-of-javascript-2019#json

Input:

```javascript

const foo = { a: "3", d: "f" };

const bar = [1, 4, -2, true, false, {}, "ok"];

```

Output:

```javascript

const foo = JSON.parse('{"a":"3","d":"f"}');

const bar = JSON.parse('[1,4,-2,true,false,{},"ok"]');

```

## Usage

```

yarn add -D babel-plugin-transform-optimize-object-literal

```

`.babelrc`:

```json

{

  "plugins": [

    [

      "babel-plugin-transform-optimize-object-literal",

      {

        "skipArrayOptimizationIfLengthIsBelow": 0,

        "skipObjectOptimizationIfLengthIsBelow": 0

      }

    ]

  ]

}

```
