# evil-eval

A JavaScript interpreter written in JavaScript.

## Why

Yout might working in a JavaScript environment where `eval()` and `new Function()` are not allowed (eg: WeChat Mini Program), and you probably have a good reason to use it.

## Usage

```js

import { runInContext } from 'evil-eval';

const code = `

    function hello(name) {

        return 'Hello ' + (name || defaultName) + '!';

    }

    module.exports = hello;

`;

const sandbox = { defaultName: 'World' };

const hello = runInContext(code, sandbox);

hello();

```
