### `find: String|RegExp`

Supply a string or RegExp to find what you are looking for

### `replace: String|Function`

Supply a string to directly replace what you've found, or a function to dynamically modify your findings

#### Example using String for both find and replace

```js
modify({
  find: 'eval',
  replace: 'lava'
})
```

#### Example using RegExp for find and a Function for replace

```js
modify({
  find: /svg\((.*?)\)/,
  replace: (match, path) => JSON.stringify(fs.readFileSync(path, 'utf8'))
})
```
