This is useful for ensuring that custom elements are named correctly before attempting to define them in the document.

"use strict"; const isPotentialCustomElementName = require('is-potential-custom-element-name'); console.log(isPotentialCustomElementName('my-element')); // true console.log(isPotentialCustomElementName('notValid')); // false
