Question

Can you apply chaining on conditional operator?

Answer 1

Yes, you can apply chaining on conditional operators similar to if … else if … else if … else chain. The syntax is going to be as below,

function traceValue(someParam) {
  return condition1
    ? value1
    : condition2
    ? value2
    : condition3
    ? value3
    : value4;
}

// The above conditional operator is equivalent to:

function traceValue(someParam) {
  if (condition1) {
    return value1;
  } else if (condition2) {
    return value2;
  } else if (condition3) {
    return value3;
  } else {
    return value4;
  }
}
