Some ways of organizing dictionaries

cyclone4.ts

// Globals
declare const foo: Function;
declare const bar: Function;
declare const dict: Object;

// Option 1 (bad)
const functions1 = [
  {fn: foo, key: 'FOO'},
  {fn: bar, key: 'BAR'}
];

functions1.forEach(o => o.fn(dict[o.key]));

// Option 2 (better)
const functions2 = {
  FOO: foo,
  BAR: bar
};

// 2.1 (using for..in)
for (var fn in functions2) {
  functions2[fn](dict[fn]);
}

// 2.2 (using Object.keys)
Object.keys(functions2).forEach(key => {
  functions2[fn](dict[fn]);
});
