A "sugar" way to use Mithril's m.component.

componentization.js

'use strict';
var m = require('mithril');

function isObject(object) {
    return {}.toString.call(object) === "[object Object]";
}

module.exports = function(component) {
    return function() {
        var args = [].slice.call(arguments),
            hasAttrs = args[0] != null && isObject(args[0]) && !("tag" in args[0] || "view" in args[0] || "subtree" in args[0]),
            attrs = hasAttrs ? args[0] : {},
            children = !hasAttrs ? args[0] : args[1];
        return m.component.call(this, component, attrs, children);
    }
}

index.js

'use strict';
var m = require('mithril'),
    cmp = require('./componentization.js');

var hello = cmp({
    controller: function(attrs, name) {
        this.hello = 'Hello ';
    },
    view: function(ctrl, attrs, name) {
        return m('div', attrs, ctrl.hello + name + '!');
    }
});

m.render(document.body,
  m('div', [
      hello('Bilbo Baggins'),
      hello({ onclick: function() { console.log('My precious!!!'); } }, 'Gandalf')
  ])
);
