About HTMLAnchorElement.prototype.searchParams

This property is already implemented in Firefox and polyfilled here only for browsers that exposes getters and setters through the HTMLAnchorElement.prototype.

In order to know if such property is supported, you must do the check as such:

if ('searchParams' in HTMLAnchorElement.prototype) {
  // polyfill for <a> links supported
}

If you do this check instead:

if (HTMLAnchorElement.prototype.searchParams) {
  // throws a TypeError
}

this polyfill will reflect native behavior, throwing a type error due access to a property in a non instance of HTMLAnchorElement.

Nothing new to learn here, just a reminder.
