Plain Javascript and JS Intializers

DEV.to has two javascript codebases. One is located at /app/javascripts and this is plain javascript being served using spockets

The plain javascript codebase is not transpiled and will be limited to whatever flavour of javascript provided by the end-user's web-browser

app/javascripts/application.js is primary packaged javascript file which should be included in the primary template located within app/layouts. application.js automatically includes all javascript files via:

//= require_tree .

One javascript file it loads is initializePage.js.erb which boostraps the majority of functionality. You will see wtihin this file it manually loads multiple files:

  initializeBaseTracking();
  initializeTouchDevice();
  initializeCommentsPage();
  initEditorResize();
  initLeaveEditorWarning();
  initializeArticleReactions();
  initNotifications();
  initializeSplitTestTracking();

Theses files are located at /app/assets/javascripts/intializers
