Personally, I don't like the nested ternary conditions. 

const result = !conditionA
  ? "Not A"
  : conditionB
  ? "A & B"
  : "A";

Instead of the nested if..else, I would prefer the "Early assignment" like "Early Exits"

let result = null;
if (conditionA) {
  if (conditionB) {
    result = "A & B";
  } else {
    result = "A";
  }
} else {
  result = "Not A";
}

// instead

let result = "";

if(!conditionA) result = "Not A";
if(!conditionB) result = "A"
result = "A & B"
