What is this?

This is a function that checks if a given character is ASCII alphanumerical: it matches [a-zA-Z0-9].

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. In Node.js (version 12.20+, 14.14+, or 16.0+), install with npm:

npm install is-alphanumerical

In Deno with Skypack:
