[`String#trimLeft()`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/trimLeft) and [`String#trimRight()`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/trimRight) are aliases of [`String#trimStart()`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/trimStart) and [`String#trimEnd()`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/trimEnd). This is to ensure consistency and use [direction](https://developer.mozilla.org/en-US/docs/Learn/CSS/Building_blocks/Handling_different_text_directions)-independent wording.

## Fail

```js
const foo = bar.trimLeft();
