Help: How do I loop simple JSON objects to iterate all keys and values itself?

There are two solutions to achieve your requirements.

#Solution 1 [Recommended]: Use Object.entries() - to convert object to array directly with one-liner question.

See live demo here

$( document ).ready(function() { var input = {"parking_space" : "16 X 25 FEET","parking_location" : "Address line items","parking_country":"CA","parking_book_start_date": "03/06/2022 10:00:00","parking_book_end_date":"03/06/2022 20:30:00"};var solution1 = Object.entries(input); console.log('Object.entries() ::: '+JSON.stringify(solution1));});

output: [["parking_space","16 X 25 FEET"],["parking_location","Address line items"],["parking_country","CA"],["parking_book_start_date","03/06/2022 10:00:00"],["parking_book_end_date","03/06/2022 20:30:00"]]

#Solution 2: Use Object.keys() - to get an array of all keys inside your object, iterate throughout all keys and get values. You need one array to manage keys and values according to your requirements. If your keys contains null values, you need a null check. inshort, this another solution is bit lengthy so I recommend to go with first solution,

Hope it will work for you.
