## Introduction

The `@supercharge/json` package is a drop-in replacement for the global `JSON` object. It protects JSON parsing against protoype pollution attacks.

## Installation

```

npm i @supercharge/json

```

## Usage

Using `@supercharge/json` is pretty straightforward. Use it the same way as you would use the `JSON` object:

```js

const JSON = require('@supercharge/json')

const user = JSON.parse('{"name":"Supercharge"}')

// { name: 'Supercharge' }

const user = JSON.parse('{"name":"Supercharge", "__proto__": { "x": 1 }, "constructor": {"prototype": {"bar": "baz"} } }')

// { name: 'Supercharge' }

const json = JSON.stringify({ name: 'Supercharge' })

// '{"name":"Supercharge"}'

```
