How to push elements in array based on the avilability

August 15, 2022

I have an array

let availabilityArray = [currentYearAvailability, previousYearAvailability, previousLastYearAvailability]
console.log(availabilityArray)

when I Console, I can able to find what is available what is not available

const preAuthAvailabilityYears =
    [
      currentYearAvailability ? currentYear : undefined,
      previousYearAvailability ? previousYear : undefined,
      previousLastYearAvailability ? previousLastYear : undefined,
    ]

I need only the availability years to be displayed in the array instead showing as undefined as third argument, If it is undefined i shouldnot should in array

>Solution :

const preAuthAvailabilityYears =
    [
      currentYearAvailability ? currentYear : undefined,
      previousYearAvailability ? previousYear : undefined,
      previousLastYearAvailability ? previousLastYear : undefined,
    ].filter(Boolean)
