How to start learning JScript?

To summarize some of the tbone's points, when using the WSH scripting (JScript or VBScript) in Opus, broadly speaking the following categories of functionality become available to you:

  1. JScript (or VBScript) core language functionality such as variables, loops etc. (see the tbone's explainer mentioning ES5) which enable more complex scripting than using just the standard internal Opus commands.
  2. Opus-specific functionality (via Opus-provided scripting API), such as DOpus.Output("Hello!")
  3. Windows system-wide functionality (via ActiveScripting), such as ability to mute/unmute audio, eject the CD drive tray etc. -- nicely integrated in Opus (e.g., trigger on button click).
