How to check if element exists in array with jq

Question

I have an array and I need to check if elements exists in that array or to get that element from the array using jq, fruit.json:

{
    \"fr         


        

Answer 1

For future visitors, if you happen to have the array in a variable and want to check the input against it, and you have jq 1.5 (without IN), your best option is index but with a second variable:

.inputField as $inputValue | $storedArray|index($inputValue)

This is functionally equivalent to .inputField | IN($storedArray[]).
