How to delete the element in the array of json object in Java-script

Recently we had a very basic requirement to delete an key value pare in the json array using Javascript.


Input data

{"invideoPromotion":{"items":[{"id":{"type":"video","videoId":"11","websiteUrl":""},"timing":{"type":"ms","offsetMs":"2222"},"customMessage":"aa","promotedByContentOwner":"vanji"}]}}

Expected business logic

When type of id is video and websiteUrl is null; websiteUrl should be removed from the payload.

Output data

{"items":[{"id":{"type":"video","videoId":"11"},"timing":{"type":"ms","offsetMs":"2222"},"customMessage":"aa","promotedByContentOwner":"vanji"}]}}

In-order to do this you can use delete functionality of the json in javascript.
