Javascript always wanted to be a functional language. But for historical, political and perhaps even sensible reasons, JS's original mission was never truly fulfilled.

But what if, we take JS and start removing things. We can remove mutation, remove variables, remove classes, remove variadic signatures, remove default arguments and on and on.

What if we go back to ES1 and re-evaluate a future unperturbed by corporate circumstance.

Icons have been part of applications since ages. Also most websites rely on icons. There were several ways to use them. First we used plain files then image sprites to reduce requests. Nowadays everyone uses icon fonts like font-awesome or glyphicons.

They are infinetly scaleable and styleable with css. The downside is they use pseudo elements for displaying. This is not only difficult to handle but also non-optimal for accessibilty.

A famous CSS-Tricks post brings SVG icons into play. The are also scalable and they behave like normal images. But we also want to have a sprite to not load any images seperatly and kill our servers and our sites performance. The proposed version is to create sprites with grunt or gulp using the symbol-trick. It's basically add every icon to a hidden sprite-image and give every icon an id-property.

// Mithril utilities
// Multi allows you to execute multiple functions as one.
// Especially useful when you want to bind several event handlers
// or run several config functions, for example binding a DOM plugin
// & assigning routing to a link.
// m( 'a.select2', {
// config : multi( m.route, select2plugin )
// }, [] );
