 ## Installation
 
 > :warning: Astring relies on `String.prototype.repeat(amount)` and `String.prototype.endsWith(string)`. If the environment running Astring does not define these methods, use [`string.prototype.repeat`](https://www.npmjs.com/package/string.prototype.repeat), [`string.prototype.endsWith`](https://www.npmjs.com/package/string.prototype.endswith) or [`babel-polyfill`](https://www.npmjs.com/package/babel-polyfill).
