## What is this?
This is a tiny package that removes final line endings (CR, LF, CR+LF) from a
string.
## When should I use this?
This package is rather niche, I found myself repeating this code when working
with a lot of markdown.
## Install
This package is [ESM only][esm].
In Node.js (version 14.14+, 16.0+), install with [npm][]:
```sh
npm install trim-trailing-lines
```
In Deno with [`esm.sh`][esmsh]:
```js
import {trimTrailingLines} from 'https://esm.sh/trim-trailing-lines@2'
```
In browsers with [`esm.sh`][esmsh]:
```html
import {trimTrailingLines} from 'https://esm.sh/trim-trailing-lines@2?bundle'
```
## Use
```js
import {trimTrailingLines} from 'trim-trailing-lines'
trimTrailingLines('foo\nbar') // => 'foo\nbar'
trimTrailingLines('foo\nbar\n') // => 'foo\nbar'
trimTrailingLines('foo\nbar\n\n') // => 'foo\nbar'
```
## API
This package exports the identifier `trimTrailingLines`.
There is no default export.
### `trimTrailingLines(value)`
Remove final line endings from `value`.
##### Parameters
###### `valeu`
Value with trailing line endings, coerced to string (`unknown`).
##### Returns
Value without trailing line endings (`string`).
## Types
This package is fully typed with [TypeScript][].
It exports no additional types.
## Compatibility
This package is at least compatible with all maintained versions of Node.js.
As of now, that is Node.js 14.14+ and 16.0+.
It also works in Deno and modern browsers.
## Contribute
