# Browser

## Overview

The browser object is a part of the [environment](environment.md). It contains
all `window` API that perform some kind of side effects. This is useful when we
need to disable/configure/modify/react to any call to these APIs. It is also
necessary to be able to mock them properly in a test environment.

```ts
console.log(env.browser); // display the content of browser
```
