Why JavaScript is needed
Hub 4 Mech is an interactive site. Without JavaScript you can still read notes and problem statements, but these parts do not work:
- search, the Explore menu and the other menus;
- checking answers, hints and step-by-step solutions;
- interactive apps and app previews;
- saving, voting, comments, sets, classes and the note editor;
- formulas may show as plain LaTeX code.
