Does ExtendScript not support default parameters in functions? i.e.:
function doSomething (a, b = null, c = 100) { // do scripty things }
I can’t get defaults to work that way, and the “old” workaround I used to use inside the function doesn’t seem to work either:
function doSomething (a, b, c) {
b = typeof b !== ‘undefined’ ? b : null;
c = typeof c !== ‘undefined’ ? c : 100;
// do scripty things
}Thanks in advance.

I believe ExtendScript is based on ye olde ES3, while default parameters are a feature of ES6, so you’re out of luck I’m afraid.
As for your workaround, that should work in JavaScript, but ExtendScript can be a strange and unpredictable beast at times. In your sample code there, I notice you have ‘smart’ quotes around ‘undefined’, but I’m guessing that’s not in your actual code? You could try testing your variables directly against undefined instead:
function doSomething (a, b, c) { b = (b !== undefined) ? b : null; c = (c !== undefined) ? c : 100; // do scripty things } -
