Encountering a Lint No Nested Ternary Error while utilizing the ternary operator

Is there a way to prevent the occurrence of the "no nested ternary" error in TypeScript?

                  disablePortal
                  options={
                    // eslint-disable-next-line no-nested-ternary
                    units=== "mm"
                      ? valuesMm
                      : units === "km"
                      ? valueskm
                      : valuesls
                  }

I attempted to use this code but encountered an error.

options={
                    units=== "mm"
                      ? valuesMm
                      : [
                          units.slumpUnit === "cm"
                            ? valuesCm
                            : valuesIn,
                        ]
                  }

Answer №1

This location seems like a perfect spot to break the norm and nest it - however, if nesting isn't your style, another approach is to incorporate the logic into an Immediately Invoked Function Expression (IIFE) and use return to output the values conditionally.

options={(() => {
  if (units === 'mm') return valuesMm;
  if (units === 'km') return valuesKm;
  return valuesLs;
})()}
