## What is this?

This package exposes an algorithm to decode numeric character references.

## When should I use this?

This package might be useful when you are making your own micromark extensions.

## Install

This package is [ESM only][esm].
In Node.js (version 16+), install with [npm][]:

```sh
npm install micromark-util-decode-numeric-character-reference
```

In Deno with [`esm.sh`][esmsh]:

```js
import {decodeNumericCharacterReference} from 'https://esm.sh/micromark-util-decode-numeric-character-reference@1'
```

In browsers with [`esm.sh`][esmsh]:

```html
<script type="module">
  import {decodeNumericCharacterReference} from 'https://esm.sh/micromark-util-decode-numeric-character-reference@1?bundle'
</script>
```

## Use

```js
import {decodeNumericCharacterReference} from 'micromark-util-decode-numeric-character-reference'

decodeNumericCharacterReference('41', 16) // 'A'
decodeNumericCharacterReference('65', 10) // 'A'
decodeNumericCharacterReference('A', 16) // '\n'
decodeNumericCharacterReference('7F', 16) // '�' - Control
decodeNumericCharacterReference('110000', 16) // '�' - Out of range
```

## API

This module exports the identifier:
[`decodeNumericCharacterReference`][api-decode-numeric-character-reference].
There is no default export.

### `decodeNumericCharacterReference(value, base)`

Turn the number (in string form as either hexa- or plain decimal) coming from
a numeric character reference into a character.

Sort of like `String.fromCharCode(Number.parseInt(value, base))`, but makes
non-characters and control characters safe.

###### Parameters

*   `value` (`string`)
    — value to decode
*   `base` (`number`, probably `10` or `16`)
    — numeric base

###### Returns

Character (`string`).

This package is fully typed with [TypeScript][].
It exports no additional types.
