  To start a command, do if (command === ``[commandtexthere]``)

  All words after the command (all strings separated by spaces) will be saved in the args[] array.
      The second word is args[0], third is args[1], etc etc.
      Generally, this is used for other information a command needs once the command is known
          eg In Tatsumaki, you can do !t avatar @username. "avatar" is the command, "@username" is the first argument (args[0])
