Do any other DAWs support scripting?

Or is this unique to Tracktion?

It's such a cool idea, I'm surprised that nobody's done anything like this before.

The only DAW scripting I can think of was Cakewalk's groundbreaking CAL scripts, but that was only for MIDI manipulation and has been deprecated for some time.

Reaper is scriptable
Live can be scripted via Max4Live or Python controller scripts
Bitwig has controller scripts

Thanks.

Can you think of any advantage to using Javascript over Python in this scenario? I'm no expert in either of them, but I've always thought of Python as being simpler to figure out and probably easier to pick up for a non-programmer.

Its six and half-a-dozen, to be honest. They're both common, robust embeddable languages.

Possibly; it was definitely intended to be. Javascript does have the advantage of being a C-style language, though, so the basic syntax has a lot of overlap with other common languages. If you're familiar with one of those, Javascript's not hard to get started with.
There's plenty of information, tutorials, etc on both, though.

Sony Vegas also supports scripting.

Renoise has Lua scripting too.
Usine Hollyhock is a modular DAW that is basically a fully programmable DAW by design.

MusE is another Linux DAW with scripting support.
