JS Nested Ternary with Multiple conditions

Question

Essentially I have the following issue:

if condition A & B are true ->. do thing A
if only condition A is true -> do thing B 
else -> do thing C

I tried this :

const myThing = conditionA ? conditionB ? thingA :
conditionA ? thingB : thingC;

It doesn't like the syntax but I am not sure what is wrong with it.

Answer 1

    const myThing = (conditionA && conditionB) ? thingA : (conditionA) ? thingB : thingC;
       

the same as:

if(conditionA && conditionB){
   thingA
}
else if(conditionA){
   thingB
} else {
   thingC
}
