Unexpected Token

Trying to run whatsapp and receiving following error:

client/scripts/lib/app.js:53:2: Unexpected token (53:2)

what does 53:2 refer to?

Line 53, and the second (or possible third, not sure) character on that line.

Thanks, I looked at the errors for the lines/characters and still do not see issue. Below are the errors and the actual lines.

  1. client/scripts/lib/app.js:53:2: Unexpected token (53:2)
    .load(RoutesConfig);

  2. client/scripts/controllers/chats.controller.js:77:13: Unexpected token, expected ; (77:13)
    remove(chat) {

  3. client/scripts/routes.js:14:6: Unexpected token, expected ( (14:6)
    class RoutesConfig extends Config {

Below are the current errors and lines.

  1. client/scripts/controllers/chats.controller.js:77:13: Unexpected token, expected ; (77:13)
    remove(chat) {

  2. client/scripts/routes.js:14:6: Unexpected token, expected ( (14:6)
    class RoutesConfig extends Config {

Resolved, just downloaded zip with clean files at https://github.com/Urigo/Ionic-MeteorCLI-WhatsApp
