The team member of jQuery Core - Timmy Willison told us
in a blog post about Query 3.0 Beta Released.
Developers with jQuery 3.0 alpha had experimented with methods like an
inline-display-none-remover (.show()) and
inline-display-none-adder (.hide()) and removing
inline display:none did not always show the element.
Fix the custom selectors like
:visible make is up to 17 times faster now.
Link jQuery with :
https://code.jquery.com/jquery-3.0.0-beta1.js
https://code.jquery.com/jquery-3.0.0-beta1.min.js
...or get the beta version from npm:
npm install jquery@3.0.0-beta1
