Javascript URL Regex

\b(https?:\/\/)?((?:www\.)?((?:[^\s.,;()\/]+\.)+[^\s$_!*()$&.,;=?+\/\#]+)((?:\/|\?|\/\?)[^\s#^`{}<>?"\[\]\/\|]+)*\/?(#[^\s#%^`{}<>?"\[\]\/\|]*)?)

/**
 * Should be used with /i flag as well as the /g flag if looking for multiple matches
 *
 * Notes:
 * Ignores schemes other than http(s).
 * Captures emails as otherwise it would match the `gmail.com` in `hi@gmail.com`,
 * producing (what I think is) more surprising behaviour than the alternative.
 *
 * Produces some false positives on tests from https://mathiasbynens.be/demo/url-regex,
 * but most of these false positives are meant to pass for practical reasons
 * (such as foo.com, http://-error-.com, etc). However this does mean that any
 * string of the format \(\w*.)+\w will pass this filter (most noticable for property
 * accessors or mistyped sentences... you can't win them all ¯\_(ツ)_/¯).
