## What is this?
|
||
|
||
This is a function that checks if a given character is a white space character:
|
||
whether it matches `[a-f0-9]`, case insensitive.
|
||
|
||
## When should I use this?
|
||
|
||
Not often, as it’s relatively simple to do yourself.
|
||
This package exists because it’s needed in several related packages, at which
|
||
point it becomes useful to defer to one shared function.
|
||
|
||
## Install
|
||
|
||
This package is [ESM only][esm].
|
||
In Node.js (version 12.20+, 14.14+, or 16.0+), install with [npm][]:
|
||
|
||
```sh
|
||
npm install is-hexadecimal
|
||
```
|
||
|
||
In Deno with [Skypack][]:
|
||
|
||
```js
|
||
import {isHexadecimal} from 'https://cdn.skypack.dev/is-hexadecimal@2?dts'
|
||
```
|
||
|
||
In browsers with [Skypack][]:
|
||
|
||
```html
|
||
<script type="module">
|
||
import {isHexadecimal} from 'https://cdn.skypack.dev/is-hexadecimal@2?min'
|
||
</script>
|
||
```
|
||
|
||
## Use
|
||
|
||
```js
|
||
import {isHexadecimal} from 'is-hexadecimal'
|
||
|
||
isHexadecimal('a') // => true
|
||
isHexadecimal('0') // => true
|
||
isHexadecimal('G') // => false
|
||
isHexadecimal('💩') // => false
|
||
```
|
||
|
||
## API

There is no default export.

||
|
||
### `isHexadecimal(character|code)`
|
||
|
||

|
||
first position (`string`), is isHexadecimal.
|
||
|
||
## Types
|
||
|
||
This package is fully typed with [TypeScript][].
|
||
|
||
## Compatibility
|
||

|
||
As of now, that is Node.js 12.20+, 14.14+, and 16.0+.
