hast utility to check if an element is script-supporting.

This package is ESM only: Node 12+ is needed to use it and it must be imported instead of required.

npm:

npm install hast-util-script-supporting

import {scriptSupporting} from 'hast-util-script-supporting'

scriptSupporting({
  type: 'element',
  tagName: 'a',
  properties: {href: '#alpha', title: 'Bravo'},
  children: [{type: 'text', value: 'Charlie'}]
}) // => false

scriptSupporting({
  type: 'element',
  tagName: 'template',
  children: [{type: 'text', value: 'Delta'}]
}) // => true

This package exports the following identifiers: scriptSupporting. There is no default export.

Check if the given value is a script-supporting element.
