Having some experience with both Python and JS/TS, I don't have much preference about ternaries or expressions. Although I always break lines for ternary statements.

const testStuff = condition ? 
  outcome(1) :
  outcome(2);

Having everything on the same line ruins readability for me.

personally I prefer

const testStuff = condition
  ? outcome(1) 
  : outcome(2);

Also works fine and is better than inlining it all. I'm just more used to ending the lines with the symbols - instead of starting the next line with them like your example - because it's the same parttern I use for other stuff, like (curly) brackets.

The if-else expression that Python has is quite different from (and significantly worse than) what people mean with if-else as an expression.

So, this is Python:

volume = 100 if user_is_deaf else 50

These are two examples of if-else as an expression (Rust and Scala):

let volume = if user_is_deaf { 100 } else { 50 };

val volume = if (user_is_deaf) 100 else 50

Crucially, these look essentially equivalent to normal if-else-statements in these languages.
