Deprecate jQuery

[Wolfr]

All JS in Bedrock's core should be written as vanilla JS, not using jQuery. This was mentioned before but this is the “official” issue to track progress.

import $ from 'jquery';

import './prototype-nav';
import './styleguide-code-samples';
import './styleguide-typography';
import './styleguide-search';
import rememberScroll from './styleguide-remember-scroll';

window.$ = $;

rememberScroll('#__prototype-nav');
rememberScroll('.br-styleguide-content');
rememberScroll('.br-styleguide-navigation-holder');

• './prototype-nav'; needs to be looked at, this is the hardest one
• Code samples is well under way (in prism branch)
• './styleguide-typography'; is done
• './styleguide-search'; needs to be looked at, should be fairly simple Rewrite styleguide-search to vanilla JS #405
• rememberScroll

Prototype nav is the one that's left, there is a PR but it doesn't work yet.
