Search through a JSON array to find a specific element and retrieve the entire array linked to that element

Recently, I've been working with a json array that dynamically increases based on user input. Here's a snippet of the json code I'm dealing with:

[{"scheduleid":"randomid","datestart":"2020-06-30","dateend":"2020-06-30","timestart":"08:00","timeend":"20:00","recurrences":"dailysett","daily":""},
{"scheduleid":"randomid2","datestart":"2020-06-30","dateend":"2020-06-30","timestart":"08:00","timeend":"20:00","recurrences":"dailysett","daily":""}]

This json array is stored in var Schedulearray. If I need to search for a specific id, such as retrieving randomid from the array, I can use the following line of code:

Schedulearray.scheduleid;

If the result is randomid, I'd like to retrieve all attributes associated with that element, like timestart, timeend, and so on. Is it possible to do this in one go, or do I have to fetch each attribute individually like demonstrated below?

var timestart=Schedulearray.timestart;
