Type syntax from TypeScript

angular2Type.js

// TypeScript types
function myFn(name:string, obj:MyClass) {
  // ...
}

// Equivalent ES5
/**
 * @param name {string}
 * @param obj {MyClass}
 */
function myFn(name, obj) {
  assert(typeof name === 'string');
  assert(obj instanceof MyClass);
  // ...
}
