the Fetch API is totally mutable and can be replaced or removed by doing

```js
window.fetch = null;

```

or,

```js
var fetch = null;

```

or, the fetch property can be removed as well.

```js
delete window.fetch;

```

This means, if a legacy code defines a global variable named `fetch`, the fetch API cannot be used.

Is there any way to access the original `fetch` function in JavaScript?
