This is a function that checks if a given character is ASCII alphanumerical:
it matches [a-zA-Z0-9].
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.
This package is [ESM only][esm].
In Node.js (version 12.20+, 14.14+, or 16.0+), install with [npm][]:
``sh`
npm install is-alphanumerical
In Deno with [Skypack][]:
`js`
import {isAlphanumerical} from 'https://cdn.skypack.dev/is-alphanumerical@2?dts'
In browsers with [Skypack][]:
`html`
`js
import {isAlphanumerical} from 'is-alphanumerical'
isAlphanumerical('a') // => true
isAlphanumerical('Z') // => true
isAlphanumerical('0') // => true
isAlphanumerical(' ') // => false
isAlphanumerical('💩') // => false
`
This package exports the following identifier: isAlphanumerical.
There is no default export.
Check whether the given character code (number), or the character code at thestring
first position (), is alphanumerical.
This package is fully typed with [TypeScript][].
This package is at least compatible with all maintained versions of Node.js.
As of now, that is Node.js 12.20+, 14.14+, and 16.0+.
It also works in Deno and modern browsers.
This package is safe.
