Definitely. JavaScript is platform-independent, and ID's support is virtually flawless, as I have scripts from way back to CS that still work.

The other choices are AppleScript -- but this is limited to Macs, VBScript -- the same for Windows (although programming in VBScript seems just a teeny weeny easier; but my office is split right down tha middle between Mac & Win), and, for advanced users only, raw handling of the COM objects in any external programming language that can handle them. The latter most likely constrains you to a single hardware platform, but what's (probably) worse is that the code will need major revising for each new version of CS.

JavaScript is concise, can be edited with any plain text editor, and help for its general functions can be found all over the web. ID specific functions can be found in the ESTK Help menu (and I should probably mention that someone re-programmed all that text into a comprehensively linked set of HTML files :-) ).

Go for JavaScript.
