Answer 1

In the examples, hearCommand is a very simple wrapper around vk.updates.hear . In implementation, it works like this:

hearCommand('test', (context) => {});
// Аналогична данной запись
vk.updates.hear(
  [
    (text, { state }) => (
      state.command === 'test'
    ),
    '/test'
  ],
  (context) => {}
);

Example with 3 arguments

hearCommand('test', /test (.+)/i, (context) => {});
// Аналогична данной запись
vk.updates.hear(
  [
    (text, { state }) => (
      state.command === 'test'
    ),
    /test (.+)/i
  ],
  (context) => {}
);
